Problem: Assume that in (Figure 1) I = 12A and d = 42cm .What is the magnitude of the force on the second wire?

FREE Expert Solution

Magnetic force on a current-carrying conductor:

FB=BiL

Magnetic field around a wire carrying current:

B=μ0i2πr

Wires carrying current attract each other if the current is flowing in the same direction. The force is repulsive if current flows in opposite directions.

The forces on wire 2 are; F1 repulsive (downward) and F3, repulsive (upward).
