Two long, parallel wires are separated by 3.0 m. Each wire has a 31-A current, but the currents are in opposite directions.

A) Determine the magnitude of the net magnetic field midway between the wires.

B) Determine the magnitude of the net magnetic field at a point 1.5 m to the side of one wire and 4.5 m from the other wire. The point is in the same plane as the wires.

Solutions

Expert Solution

This problem can be solved by using the formula for direction and magnitude of magnetic field produced by a long wire carrying a current I. For part A, the magnitude of net magnetic field turns out to be 8.27 X 10^(-6) Tesla and for part B, the magnitude of the net magnetic field turns out to be 2.753 X 10^(-6) Tesla. Detailed solution given below. Ask me if you have any doubts. Feedback will be helpful.
