Question

Select all correct statements for the current in the loop. Enter your response as an alphabetical list with no spaces. In figure 2 the B field points into the page as denoted by the x's. The field is stronger where the x' s are closer together. A) fig. 1: Magnet moving to the left, induced current 'a'. B) fig. 2: Loop moving down, no induced current. c) fig. 2: Loop moving up, induced current 'b'. D) fig. 2: Loop moving to the right, induced current 'b'. E) fig. 1: Magnet moving to the right, induced current 'a'. F) fig. 1: Loop moving to the left, induced current 'a'.

Explanation / Answer

The correct options are BDEF

because

B) Distance between magnet and loop remain same, so no changing magnetic field, no current induced

D) Loop moving to right means, N-pole moving towards loop, so induced current is in anticlockwise sense.(By Lenz's law)

E) Similar reason as given for D

F) Similar by Lenz's law
