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. Conclusionĭuring part one of the experiment, magnetic field strength was measured as a function of radial distance from a conductor. The value is 6.7 x 10 -5 T/turn, which is very similar yet slightly large in value than the slope. How does it compare to the slope of your graph? What is the percent difference? The graph of the slope is 6.53 x 10 -5 T/turn.Ĥ. For your data from Part 2, plot a graph in Graphical Analysis of B vs. The exact dependence of the magnetic field strength B on the number of turns N is B = Nμ oI/ 2R where R is the radius of the loop of wire. 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. The value is 1.4 x10 -6 Tm, which is larger in value in comparison to the slope.

For your data from Part 1, plot a graph in Graphical Analysis of B vs. The exact dependence of the magnetic field strength B on radial distance from the wire R is B = μ oI / 2πR where μ o is the permeability of free space and has a value of 4π x 10 -7 Tm/A. Theory states that the magnetic field produced by a long straight current-carrying wire decreases in strength as you get further from the wire.
