Question

Two long, straight wires are parallel and 38 cm apart. (a) If each wire carries a current of 52 A in the same direction, what is the magnitude of the magnetic force per meter (in N/m) exerted on each wire?

Answer 1

Answer: 1.42×10^–3 N/m

Explanation:

Given data:

Distance between both wires = 38cm = 0.38m.

Current in both wire ( I ) = 52A.

Solution:

F/L = μ0I^2/2πr

= 4π×10^−7 * ( 52 )^2 / 2π (0.38)

= 3.398×10^-3 / 2.388

= 1.42×10^–3 N/m
