Question

A short segment of a thin wire runs through a region of uniform magnetic field oriented perpendicular to the wire segment. If the magnitude of the magnetic field is 2.34 T, and the magnetic force per unit length on the wire segment is 0.367 N/m , calculate the current in the wire.

Answer 1

Here,

let the current in the wire is I

for the magnetic force per unit length = B * I * sin(theta)

0.367 = 2.34 * I * sin(90 degree

I = 0.154 A

the current in the wire is 0.154 A
