Two parallel wires are 6.8 cm apart, and

each carries a current of 23.8 A.

The permeability of free space is 4pi ×

10−7 T · m/A.

If the currents are in the same direction,

find the force per unit length exerted by one

of the wires on the other.

Answer in units of N/m.

2. Relevant equations

F/L = (permeability)/(2*pi*d) * 2I

3. The attempt at a solution

F/L = (4*pi*10^-7 T*m/A)/(2*pi*0.068m) * 2(23.8 A)

= 0.00014 N/m
