Magnetic force on a current-carrying conductor:
Magnetic field around a wire carrying current:
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).
Assume that in (Figure 1) I = 12A and d = 42cm .
What is the magnitude of the force on the second wire?
