Use the controls on the Magnetic Field Sensor (hardware) to set it to radial mode and 10× reading. The purpose of the Magnetic Field in a Slinky lab is to determine the relationship between the magnetic field and the current in a solenoid, determine the relationship between the magnetic field and the number of turns per meter in a solenoid, study how the field varies inside and outside a solenoid, and determine the value of µ0 (the permeability constant). The field then gets measured off- center to discover if the field remains uniform within a radial direction. Where is the field strongest around the magnet? 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. Disclosure: As an Amazon Associate I earn from qualifying purchases. through a wire, a magnetic ﬁeld is produced in the region around the wire. The data followed the expected trend of decreasing in magnetic field strength as the radius increased. Physics 15b Lab 3: Magnetic Fields and Induction In Chapter 5, Purcell uses relativity to derive the force acting between two moving charges, given the forces and charge densities in a stationary frame. The white dot of the sensor was aligned to be in the center of the cylindrical support with the white dot facing upward. Conclusion.

The resulting slope was 9.2 x 10-7 Tm and the correlation was 0.9734. This meant verifying that the field inside a toroid (effectively an infinite wire) varied with the inverse of the radius. Draw the magnetic field of a horseshoe magnet in the diagram below. Steady magnetic ﬁelds like those we will study in this experiment are created by steady currents of charged particles. The intensity of a magnetic field gets measured from three separate coil spacings, where each distance creates its own magnetic field. Electromagnets Notes For A Levels. 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. Magnetic fields can be represented by magnetic field lines. For your data from Part 1, plot a graph in Graphical Analysis of B vs. 1/R. Your graph should have a linear trend. Paul J.

Laboratory #6 Magnetic Fields Objective This experiment has 2 parts: (1) you will map the magnetic ﬁelds around a bar magnet and a current-carrying coil, and (2) you will measure induced currents using a bar magnet and a galvinometer. During part one of the experiment, magnetic field strength was measured as a function of radial distance from a conductor. Magnetic field of a straight wire. The percent difference is 41%. Two charged particles travel with some velocity, , through a uniform magnetic field, .As the charges pass through the magnetic field, each experiences a magnetic force, , due to their velocity, the direction and strength of the magnetic field and their charge, .Note that here the positive charge experiences an upward magnetic force and the negative charge experiences a downward force. It would have been a nice followup, and highlight to readers how you adapted to change in your project. By the way, I think that Mathematica will add the vector fields if you define a new field which is the sum of two fields. 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. Perform a Linear Fit on your graph. 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. x = 100 mm. 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 Hall effect will be used to find this field. A piece of flexible wire was wound around the outside of this support to complete one full turn. 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. Magnetic ﬂux can be thought of as the number of magnetic ﬁeld lines passing through a given area. Fig. 3. 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. The purpose of this lab is to explore the relationship among force exerted on a current-carrying wire, magnetic field strength, and the length of the wire. For your data from Part 2, plot a graph in Graphical Analysis of B vs. N. Your graph should have a linear trend. The strength of a magnetic field in a solenoid can be determined by Ampere's Law: B = μnI. The paper was then secured to the apparatus using tape. 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. How does it compare to the slope of your graph? 11.5 Magnetic Force on a Current-Carrying Conductor. Theory states that the magnetic field produced by a circular loop of current- carrying wire increases in strength as the number of turns of wire is increased. Figure 1. The graph of the slope is 6.53 x 10-5 T/turn. Steady magnetic ﬁelds like those Theory states that the magnetic field produced by a long straight current-carrying wire decreases in strength as you get further from the wire. LABORATORY V MAGNETIC FIELDS AND FORCES Lab V - 1 Magnetism plays a large part in our modern world's technology. 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. magnetic field at the center of a circular coil of wire (B c in Fig. The percent difference is 2.6%. 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. Highlight “H(orizontal Intensity)”, and click on “Compute Magnetic Field Components.” Report the value of … 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. 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%. As the number of turns in the coil increases, the magnetic field strength will increase, in accordance with the equation B = NμoI / 2R. 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. If the magnetic field is strong enough and additional non-magnetic forces (gravity, etc.) CSEC Physics Lab - Mapping the magnetic fields of a bar magnet 1. In the Magnetic Field Sensor’s setup window, set the Gain to 10x and, under the 1, 2, 3 or 4 cross each other? During part two of the experiment, magnetic field strength was measured as a function of the number of turns in a wire. Meiosis. Magnetic fields can be represented by magnetic field lines. The resulting slope was 6.53 x 10-5 T/turn and the correlation was 0.9943. I think that is very important to be able to do, from the perspective of general problems-soling processes. 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. 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 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. What is the value of the slope? INTRODUCTION In these exercises, you will study the magnetic field of bar magnets and the earth. 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. One gauss is equal to 1 x 10-4 Tesla. QUESTIONS: 1. I was only able to successfully plot the magnetic field due to a line of charge rather than a cylinder since I was having trouble making Mathematica plot piecewise vector functions. I also learned that while something may seem simple at first in theory, it can be very complicated to achieve in reality. The plot below was all that I had to work with. 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 […] Physics E401 Magnetic Fields and Magnetic Force Analysis/Conclusion. 1. The following lab manual can be printed. When you studied the electric eld you learned that the magnitude of the The data collected correlated strongly to the hypotheses, albeit with percent errors reaching as high as 20% [uncalibrated].
