A bar magnet is mounted on the end of a coiled spring in such a way that it moves with simple harmonic motion along the axis of a loop as shown in Figure.

(a) Make a qualitative graph of the flux fm through the loop as a function of time. Indicate the time t1 when the magnet is halfway through the loop.

(b) Sketch the current I in the loop versus time, choosing I to be positive when it is counterclockwise as viewed fromabove.
