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 1 are; F2, repulsive (upward) and F3, attractive (downward)
Assume that in (Figure 1) I = 12A and d = 42cm .
What is the magnitude of the force on the first wire?
