Question

A magnet is bouncing up and down on a spring through a copper coil.

a) Draw the position of the magnet as a function of time.

b) Draw the current as a function of time using an equal time axis as you used in j). You do not need any numbers just relative magnitude and direction.

c) Assume that the magnet has a mass of 20g and the spring constant is 2N/m. What is the frequency of the emf in the loop. Is it the same as the frequency of the magnet bouncing up and down on the spring? Do you expect the emf-versus-time curve to be a sinusoidal curve? Explain your answer.
