Two power lines run parallel for a distance of 254 m and are separated by a distance of 40.0 cm. If the current in each of the two lines is 140 A and if they run in opposite directions, determine the magnitude and direction of the force each wire exerts on the other.

To solve this problem we will apply the concepts related to the electromagnetic force given between two cables. For this purpose we will consider the following mathematical relation,

Here,

= Permeability at free space

= Current

L = Length

d = Distance between them

With our values we have,

Therefore the force between the wires is 2.4892 N as the current flows in oposite direction, the force is away from each other.
