To measure and determine the relationship between a magnetic field generated by a line of current and a radial distance from a conductor, and to measure and determine the relationship between a magnetic field at the center of a coil and the number of turns in a coil. In the visual on the left you can see a surface covered with iron filings. Orient the Helmholtz coils (HC) so as to eliminate the influence of the Earth's magnetic field on the experiment. Rather than placing two identical current-carrying wires next to each other, I made one of them have a negative current. 7.2 Introduction Note: For this experiment, you will write a complete (formal) lab report and hand it in at the next meeting of your lab section. During part one of the experiment, magnetic field strength was measured as a function of radial distance from a conductor. The standard MKS unit for a magnetic field is Tesla. The data collected correlated strongly to the hypotheses, albeit with percent errors reaching as high as 20% [uncalibrated]. The purpose of this lab is to investigate magnetic fields around simple geometric configurations of wires carrying current. 2. Magnetic fields can only exert a force on a moving charge. High magnetic field science and technology are thriving in the United States today, and the prospects are bright for future gains from high-field research. Mapping the Magnetic Field Vector Fields The electric eld, E~, and the magnetic eld, B~, are two examples of what are termed vector elds, quantities which have both magnitude and direction (hence are vectors) that can be assigned to every point in a region of space. Figure 1. Little did I realize that while I knew that these fields should look like theoretically, modelling them would have been a great undertaking. 98 Experiment 18: Earth’s Magnetic Field Advance Reading Text: Magnetic field, vectors, right-hand rule for a wire loop, resistivity. Data Table 4 Magnetic Field Lab. The magnetic field sensor measured B using “Events with Entry” on Lab Pro. Double-click on the Magnetic Field Sensor on the computer screen, and check that the 10× measurement appears in the “Data” column. A magnetic field exerts forces on a compass needle such that the needle tends to align itself with the direction of the field. Possible sources of error include the difficulty of aligning the sensor perfectly along the radius of each circle, and it was also a challenge to get an accurate reading from the sensor as the readings kept jumping around. This experiment is all about magnets, wherein it revolves on two principles of magnetisms which are the magnetic fields and the magnetic force. According to Faraday’s Law a change of the magnetic flux through an area bounded by closed circuit induces a voltage that drives the flow of current around the circuit. and click on “Compute Magnetic Field Components.” Report the value of i in Table 3. In this experiment we studied magnetic fields and learned how to predict the direction of the magnetic force on a moving charge. 3. The paper was placed on the plastic table of the apparatus and was aligned using a compass so that the parallel lines on the sheet were pointing north. As the number of turns in the coil increases, the magnetic field strength will increase, in accordance with the equation B = NμoI / 2R. shown in Fig. Magnetic field of a straight wire. The slope from this plot in comparison to the value of μoI / 2R, 6.7 x 10-5 T/turn, yielded a percent difference of only 2.6%. Conclusion. An electrical current produces a magnetic field around the wire. In this lab we will have a disk magnet (a dipole) suspended on a spring, which we will use to observe forces on dipoles due to different magnetic field configurations. The Earth’s magnetic field is not completely understood, but is thought to be associated with electrical currents produced by the rotational effects in … The purpose of this experiment is to mea-sure the horizontal component of the earth’s magnetic fleld BH using a very simple apparatus. Determine which side of the compass (either blue or silver) points along the magnetic field lines. Place a bar magnet on a piece of white paper or graph paper. One gauss is equal to 1 x 10-4 Tesla. 28 Magnetic Field in a Coil. Figure 1. The percent difference is 41%. While the topic of my project was by no means a very complicated one, it would be false to say that I did not learn anything from it. A piece of flexible wire was wound around the outside of this support to complete one full turn. The value is 6.7 x 10-5 T/turn, which is very similar yet slightly large in value than the slope. Which theoretical model (single coil or long coil) explains the magnetic field of short coil (used in this experiment)? Drag a digits window to the Magnetic Field … Electromagnets Notes For A Levels. Experiment on relationship between magnetic field and current in a Slinky Abstract A current carrying conductor possesses an associated magnetic field around it in accordance to the Biot-Savart law. 1. The exact dependence of the magnetic field strength B on the number of turns N is B = NμoI/ 2R where R is the radius of the loop of wire. Additionally, the wire was not perfectly wrapped around the base, which would throw the readings off as it would not have been an exact turn of the wire. The magnetic field sensor was zeroed and the DC power supply was set to 7 A. My main interests at this time include reading, walking, and learning how to do everything faster. This is simply the induction process. First, a piece of polar graph paper with concentric circles starting at a diameter of 0.5 cm increasing in increments of 0.5 cm to 10 cm was punched through a rigid aluminum conductor at the center of the concentric circles. If the magnetic field is strong enough and additional non-magnetic forces (gravity, etc.) 2. Thus, increasing the current will result to an increase in magnetic field in that area which increases the magnetic force in return. Draw the magnetic field of a horseshoe magnet in the diagram below. The high amperage DC power supply was connected in series with a high power resistor and the aluminum wire at the side and on top of the apparatus. Diameter of Cylindrical support = 0.130 m. 1. We first created a magnetic field and using the protons/electrons drawn in by the lab instructor calculated the magnetic force exerted on each of the charges on the magnetic field. During part two of the experiment, magnetic field strength was measured as a function of the number of turns in a wire. through a wire, a magnetic field is produced in the region around the wire. Magnetic fields can be represented by magnetic field lines. It was somewhat difficult to get accurate readings at the smaller radii, which negatively affected this correlation. Why do right and left radial magnetic fields look the way they do? As seen in my previous Final Data post, I was able to show that if identical current-carrying wires were aligned next to each other, their resulting magnetic field would resemble that of the field due to a plane of current as the distance between them decreases. Then the dipole moment can be calculated from the slope of a plot of B vs. € 1/z3. Percent Difference = |E2 – E1| / [ (E1 + E2) / 2 ] x 100%, More from…Dr. Objective The objective of this lab is to measure the magnitude of Earth’s magnetic field in the lab. Simply measure the magnetic field at various distances along the axis through the center of the magnet. The sensor was zeroed and the power supply was turn on to 7 A. 1. 2. 4, the field at the center point between the coils will be nearly homogeneous.1 H. von Helmholtz (1821-1894) realized that there 1 The symmetry of the arrangement makes the first derivative of the field with respect to the axial direction vanish. In the last part of the experiment the magnetic field of a standard bar magnetic will be measured. I think that is very important to be able to do, from the perspective of general problems-soling processes. through a wire, a magnetic field is produced in the region around the wire. Perform a Linear Fit on your graph. The conclusion is that the magnetic field is essentially uniform inside of the coil and fringes like a magnetic dipole outside of the coil. This meant verifying that the field inside a toroid (effectively an infinite wire) varied with the inverse of the radius. Discuss your drawing with a TA. As the distance from the center of the conductor increases, the magnetic field strength will decrease in accordance with the equation B = μoI / 2πR.

You will draw field lines and analyze their meaning. If you click on the magnet control, you will see the lines of force because Part I: Mapping Magnetic Fields Warning: These field maps must be done on the wooden lab benches; the metal tables interfere with the magnetic fields. B is the magnetic field, μ is the permeability constant, n is the turn density of the solenoid, and I is the current. The purpose of this lab is to investigate magnetic fields around simple geometric configurations of wires carrying current. Overall, I think you did a very good job of adapting the project as you worked through it and of discussing why you did what you did/what it means. The resulting slope was 6.53 x 10-5 T/turn and the correlation was 0.9943. Orient the Helmholtz coils (HC) so as to eliminate the influence of the Earth's magnetic field on the experiment. 1.

It would have been a nice followup, and highlight to readers how you adapted to change in your project. Why do right and left radial magnetic fields look the way they do? Possible error could have resulted from the earth’s magnetic field. Lab Report#1 Pcs130 magnetic field - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. The paper was then secured to the apparatus using tape. Ronaldo Degazon Friday 31/01/12 Physics Lab #17 Discussion: A magnetic field is the region or space around a magnet where the effects of the magnet can be experienced by any magnetic material. To do this, use a magnetic compass to determine the direction of the Earth's field, mark its direction on your work station with paper tape, and record … LABORATORY V MAGNETIC FIELDS AND FORCES Lab V - 1 Magnetism plays a large part in our modern world's technology. The magnetic eld is our way of describing the condition of space around a bar magnet or around any moving charge, such as the moving charges in a current. Equipment: 1 wire stand 6-9 small compasses 1 power supply 1 3-dimensional compass Exploration 2: The magnetic field of a current-carrying wire Exploration 2.1 The Earth’s magnetic field Calculate your value of μoI / 2R. Magnets exert attractive or repulsive forces on each other. In the Hall effect, when an electric current is driven through a small piece of semiconductor in a magnetic field, a voltage appears perpendicular to … To perform this measurement, open DataStudio and setup a Magnetic Field Sensor. 1) depends on the coil current (I), the coil radius (R) and the number of loops that make up the coil (N) Bc = NµoI 2R (1) Recall the SI unit for magnetic field is the Tesla (T) and € µ 0 =4π×10 −7Tm/A is the magnetic permeability of free space. Your graph should have a linear trend. The diameter of the cylindrical support was also measured, being 0.013 m. Graphical Analysis was used to plot B vs N and perform a linear trend. The Biot and Savart law explains how a magnetic field relates to current, and can be represented by: My understanding of how Mathematica functions as a program has grown and I have come to appreciate its capabilities. Lenz’s law of electromagnetic induction states that the direction of this induced current will be such that the magnetic field created by the induced current opposes the initial changing magnetic field which produced it. ADAM CAP is an elastic waistband enthusiast, hammock admirer, and rare dingus collector hailing from Berwyn, Pennsylvania. The direction of the magnetic field at the center of the circular loop can be obtained by applying the same right-hand rule as for a straight wire: Imagine grasping the wire in your right hand with your thumb in the direction of the current and then your fingers curl around the wire in the direction of the magnetic field. I also learned that while something may seem simple at first in theory, it can be very complicated to achieve in reality. the lab is about measuring the magnetic field created by the current running through the coil using vernier and logger pro. I would then plot their resulting vector fields and change the viewpoint such that only the x,y plane was seen. To measure the magnitude and approximate orientation of the Earth’s magnetic field in classroom. Steady magnetic fields like those we will study in this experiment are created by steady currents of charged particles. Magnetic fields are produced by the motion of electrical charges (see the next unit on electromagnetism). High magnetic field science is having an important impact in many disciplines, including medicine, chemistry, and condensed-matter physics. Introduction All magnetic fields arise from the motion of electric charges. In class you calculated the magnetic field along the axis of a coil to be given by: 2 0 223/2 1 axial 2() NIR B zR µ = + where z is measured from the center of the coil. E. Use the "manual graph" file to plot a graph of B vs. x (magnetic field on the vertical axis. The plate sees a changing magnetic field which creates a current in the plate, which creates its own magnetic field opposing the one that created it. 3. When I started this project I initially had the intention to model the magnetic fields due to a cylinder, bar magnet, and sphere. Highlight “H(orizontal Intensity)”, and click on “Compute Magnetic Field Components.” Report the value of … The magnetic field sensor was inserted into the side of the cylindrical support by screwing it into the side of the top table support using a threaded plastic bushing. Both were very difficult to find the magnetic field for at any given point and so I was at a loss for things to model. Which theoretical model (single coil or long coil) explains the magnetic field of short coil (used in this experiment)? Magnetic field of a wire loop. A magnetic field exerts forces on a compass needle such that the needle tends to align itself with the direction of the field.

The exact dependence of the magnetic field strength B on radial distance from the wire R is B = μoI / 2πR where μo is the permeability of free space and has a value of 4π x 10-7 Tm/A. The data followed the expected trend of increasing in magnetic field strength as the number of turns increased. The first part of the experiment required to verify the equation for a magnetic field due to a long straight wire given by Ampere’s Law and Biot-Savart’s law. High magnetic field science and technology are thriving in the United States today, and the prospects are bright for future gains from high-field research. First, the power supply was turned off and the center aluminum wire was removed along with the top table of the tangential galvanometer. To do this, use a magnetic compass to determine the direction of the Earth's field, mark its direction on your work station with paper tape, and record … x = 100 mm. Analysis and Conclusion: Write a summary of the entire experiment and explain what you understood and learnt from this experiment. A great example of Lenz’s law is to take a copper tube (it’s conductive but non-magnetic) and drop a piece of steel down through the tube. When you studied the electric eld you learned that the magnitude of the Lab Report 5 Magnetic Fields Physics 262-003 Author: A. Coughran Lab Partners: E. Ortiz, H. Barham Date: 4/12/17 Lab Report 5 A. Coughran 4/12/17 Objective: The objective in Lab 5 is to measure and determine the strength and location of magnetic fields using a coil, solenoid, and magnets. With the current on and kept constant, the magnetic field strength was recorded at each circle on the polar graph paper by holding the sensor in line with the parallel lines on the sheet and so that the white dot on the sensor was on the left and at a 90o angle with the parallel lines pointing north. Don't forget to rate and comment if you interest with this lab report sample. The value is 1.4 x10-6 Tm, which is larger in value in comparison to the slope. Finally, it was difficult to align the sensor perfectly in the middle of the support, so again this would contribute to some error in the readings. Additionally, if the sheet was not perfectly aligned northward, there would be interference from the earth’s magnetic pull which would have affected the readings. Ronaldo Degazon Friday 31/01/12 Physics Lab #17 Discussion: A magnetic field is the region or space around a magnet where the effects of the magnet can be experienced by any magnetic material.

Lab 5 - Magnetic Force 1. The data followed the expected trend of decreasing in magnetic field strength as the radius increased. The Hall effect will be used to find this field. The magnitude of this magnetic field is dependent on current through the conductor which in turn is dependent on the potential difference supplied and the resistance […] Conclusion The purpose of the experiment was to study and analyze magnetic fields, forces and Faraday’s Laws. The only problem I faced was that I could not find a way to superimpose the vector fields from my aligned wires. The sphere could have been modeled in two different ways: as a rotating sphere of charge, or a collection of current-carrying loops. Magnetic Field are negligible, then the compass needle points for all practical purposes in the direction of the field. However, I suspect that if I found a function Mathematica that would do this for me, I would have indeed modeled a magnetic dipole. PHYS 1493/1494/2699: Exp. Graphical Analysis was used to plot B vs. 1/R and perform a linear trend. The resulting slope was 9.2 x 10-7 Tm and the correlation was 0.9734. The plot below was all that I had to work with. Analysis and Conclusion: Write a summary of the entire experiment and explain what you understood and learnt from this experiment. Little did I realize that while I knew that these fields should look like theoretically, modelling them would  have been a great undertaking. I think the only thing that I would have done differently is to have still compared to Peter’s results, even though your project parameters changed. 3.
