Question

The figures below show two different situations where a current may be induced in a loop by Faraday's Law, with the direction determined by Lenz' Law. The magnetic field is shown by the x's in Fig. 2. Choose true or false for each statement for the current in the loop. (The compass directions are defined in the usual way.)

True or false:

a) fig1: Loop moving East, induced current a.
b) fig2: Loop moving East, induced current b.

c) fig2: Loop moving North, induced current a.

d) fig2: Loop moving West, induced current a.

e) fig2: Loop moving South, induced current a.

f) fig2: Loop moving South, induced current b.

NOTE: net current will be zero is NOT an option
