A magnetic field exerts forces on a compass needle such that the needle tends to align itself with the direction of the field. Magnetic fields are produced by electric currents; a simple segment of current-carrying wire will generate around it a circular magnetic field in accordance with the right hand rule.. You can create a stronger magnetic field by taking wire and forming it into a coil; the field is more concentrated in the center of the loop than outside the loop. Figure 1. To perform this measurement, open DataStudio and setup a Magnetic Field Sensor. 28 Magnetic Field in a Coil. 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). QUESTIONS: 1. 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. 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 … 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. Graphical Analysis was used to plot B vs. 1/R and perform a linear trend. When I started this project I initially had the intention to model the magnetic fields due to a cylinder, bar magnet, and sphere. An electrical current produces a magnetic field around the wire. 1.

It would have been a nice followup, and highlight to readers how you adapted to change in your project. Conclusion. This meant verifying that the field inside a toroid (effectively an infinite wire) varied with the inverse of the radius. 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. Calculate your value of μoI / 2R. Why do right and left radial magnetic fields look the way they do? Drag a digits window to the Magnetic Field … Fig. Thus, increasing the current will result to an increase in magnetic field in that area which increases the magnetic force in return. Meiosis. At least that’s how I got the field outside the torus of my model to be zero (field1 was the torus, bCart2 was piece-wise defined as negative bCart1 or zero, depending on the location). In this experiment we studied magnetic fields and learned how to predict the direction of the magnetic force on a moving charge. Magnetic Field Conclusions When I started this project I initially had the intention to model the magnetic fields due to a cylinder, bar magnet, and sphere. The data collected correlated strongly to the hypotheses, albeit with percent errors reaching as high as 20% [uncalibrated]. Perform a Linear Fit on your graph. 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. 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. This experiment is all about magnets, wherein it revolves on two principles of magnetisms which are the magnetic fields and the magnetic force. The sphere could have been modeled in two different ways: as a rotating sphere of charge, or a collection of current-carrying loops. 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. Using a Helmholtz coil, a calibration constant is determined that is applied to deflection values obtained by a ballistic galvanometer.
