When an electric current is flowing through a wire, there is a magnetic <em>field</em> produced. The lines of magnetic force are circles around the wire.
Answer:
188 A
Explanation:
Parameters given:
Length of cable, L = 0.78 m
Angle, θ = 60º
Magnetic field, B = 5.5 * 10^(-5) T
Force experienced by wire, F = 7 * 10^(-3) N
The force experienced by a current carrying wire of length L, due to a magnetic field B is given as:
F = I * L * B * sinθ
=> I = F/(L * B * sinθ)
I = (7 * 10^(-3)) / (0.78 * 5.5 * 10^(-5) * sin60)
I = 188 A
