Question

A bar magnet falls through a circular loop .

(a) describe qualitatively the change in magnetic flux through the loop when the bar magnet is above and below the loop.

(a) make a qualitative sketch of the graph of induced current in the loop as a function of time, choosing current to be positive when it's direction is counterclockwise a s viewed from above

Answer 1

(a) The change in magnetic flux through the loop is increasing when the bar magnet is above and decreasing when it is below the loop.

(b)
