Concept

Problem: Four loops are moving relative to a wire carrying a constant current to the right as shown.What are the direction, clockwise (CW) or counterclockwise (CCW), of the induced EMFs in the four loops, A, B, C, D?a. CW, CW, CCW, CCWb. CW, CCW, CCW, CWc. CCW, CW, CW, CCWd. CCW, CCW, CW, CW

FREE Expert Solution

For this problem, we are going to apply Lenz's law of electromagnetic induction.

Lenz's law: The induced electric current flows in a direction such that it opposes the change in flux that induced it.

Right-hand rule for currents in a loop: The thumb points in the direction of the magnetic field, fingers curl in the direction of the induced current.
