Question

A current of 7.0A flows through each of two parallel long wires The wires are 3.5cm
apart. Calculate the force acting per unit length of each wire. What will be the nature of the
force if both currents flow in the same direction?​

Answer 1

Explanation:

F/l is the force per unit length between two parallel currents I1 and I2 separated by a distance r . The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and plasmas.
