Unformatted text preview: o mimic an infinitely long straight current. The torodial coil is connected to a multimeter to measure its resistance. Next, a voltage of around 15 V was supplied to the coil, as a large voltage will cause the machine to override itself. At a constant radius ρ, the magnetic field reading should not vary. When taking measurements, the Hall probe’s flat side has to be vertically and perpendicular to the magnetic field. The torodial coil can be viewed with 3 regions with radial distance r. The first region r < a is from the center to a, where no wires (no current) is enclosed. The second region is a < r < b, this region is between the inner and outer coils. The last region is r > b, which is out of all the...
