Four very long current-carrying wires in the same plane, Ask an Expert

Academics

Four very long, current-carrying wires in the same plane intersect to form a square with side lengths of 48.0cm , as shown in the figure (Figure). The currents running through the wires are 8.0 A, 20.0 A, 10.0 A, and I.

Part A Find the magnitude of the current I that will make the magnetic field at the center of the square equal to zero.

Part B What is the direction of the current I?
