A circular loop of radius 21 cm is located in the plane of the paper inside a homogeneous magnetic field of 0.3 T pointing into the paper. It is connected in series with a resistor of 127 W. The magnetic field is now increased at a constant rate by a factor of 2.4 in 27 s.

a) Calculate the magnitude of the induced emf in the loop during that time.

b) Calculate the current induced in the loop during that time.

c) Calculate the average induced voltage when the magnetic field is constant at 0.72 T while the loop is pulled horizontally out of the magnetic field region in 9.3 s.
