Question

A rectangular loop of unknown length L.. The Loop is moving with F in the positive x-axis.

A) What is the direction of the current running through the loop? Explain Why.

B) What is the magnitude of the current running through the loop?

SHOW ALL WORK! A rectangular wire loop of unknown length L, width w, and a resistance Of R = 3 Omega is pulled out of a constant, uniform magnetic field with Velocity v. The magnetic field is of unknown magnitude B, points Into the plane of the paper, and is confined to the rectangular region As shown. Work must be done on the loop at the rate of 1 2 JIs (F . V = 12 J/s ) to move it through the magnetic field. y 1. What is the direction of the current running through the loop? Explain how you know.

Explanation / Answer


A. direction of current is counter clockwise

B> apply Power = Fv = i^2R


so i^2 = 12/3


i^2 = 4


i = 2 Amps
