Ask your teacher two long, straight wires are parallel and 11 cm apart. one carries a current of 2.9 a, the other a current of 5.3 a. (a) if the two currents flow in opposite directions, what is the magnitude (in n/m) and direction of the force per unit length of one wire on the other? magnitude n/m direction (b) what is the magnitude (in n/m) and direction of the force per unit length if the currents flow in the same direction? magnitude n/m direction

The magnitude of force per unit length of one wire on the other is and the direction is away from one another

The magnitude of force per unit length of one wire on the other is and the direction is towards each other.

Explanation:

= Vacuum permeability =

= Current in first wire = 2.9 A

= Current in second wire = 5.3 A

r = Gap between the wires = 11 cm

Force per unit length

The magnitude of force per unit length of one wire on the other is and the direction is away from one another

The magnitude of force per unit length of one wire on the other is and the direction is towards each other.

0.11 m/s and 0.28 m/s should be correct
