a.) Consider a circular current loop of radius 10.5 cm with 200total turns. Assume that the current though the coil is I. What isthe magnitude of the magnetic field at the center of the coil? (Your answer should be a numerical value multiplied by the currentI)

b.) A time varying current of the form I(t) = I_0sin(2*pi*f*t)is passed through the circular coil in part a) where I_0 = 10mA.using your result from a), write down the expression for the timevarying magnetic field B(t) at the center of the coil.

c.) A small 1.5 cm radius circular current loop is placed at thecenter of the large current loop from part a) oriented so that theplane of the current loop is perpendicular to the magnetic field.Assume that the magnetic field from the large current loop isconstant over the small loop. What is the magnetic flux through thesmall current loop? (use your result from part b)

d.) What is the total induced emf in the small current loopassuming that it has 2000 turns? (use your result from part c) Thefrequency of the time varying current is f = 1000 Hz. (Your answershould be in the form of a numerical value times a trigonometricfunction of 2*pi*f*t)
