Question

two long parallel wires are at a distance of 0.1m and a current of 5A is flowing through each. The force per unit length due to this wires will be

Answer 1

Answer:

The force per unit length acting on the wire is given as:

F=  4π μ  0  .a 2i  1  i  2 =  0.1 10  −7  ×2×5×5

​=5×10  −5  N/m
