Two parallel wires, 5.8 mm apart, carry currents of 100 A and 140 A respectively, in opposite directions. The force per unit length in N/m of one wire on the other is:

Expert Solution

For this question , we would require the magnetic field due to a wire at a point which is at a distance d from it,

The formula for the magnetic field is as follows,

,

And the concept of force on a current carrying wire in a magnetic field which is given by the formula,

.

Please find the attached images for full explaination.

So , The force between the wires will be repulsive and will have a magnitude of about 0.48N/m.
