Question

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

1) True False  fig2: Loop moving North, induced current 'b'.
2) True False  fig1: Loop moving West, induced current 'a'.
3) True False  fig1: Magnet moving West, induced current 'a'.
4) True False  fig2: Loop moving South, no induced current.
5) True False  fig1: Magnet moving East, induced current 'a'.
6) True False  fig2: Loop moving East, induced current 'b'.

Explanation / Answer

Lenz's Law: The direction of produced emf due to change in flux is such that it oposes the change which produces it.

so using that concept.

(1) True

(2) True

(3) False

(4) False

(5) True

(6) True.
