A 33-turn circular coil of radius 3.60 cm and resistance 1.00 ? is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time according to the expression B = 0.010 0t + 0.040 0t2, where B is in teslas and t is in seconds. Calculate the induced emf in the coil at t = 5.80 s. mV

An emf is induced by rotating a 1.20×10^3 turn, 23.0 cm diameter coil in the Earth’s 5.00×10^-5  T magnetic field. What average emf is induced, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 12.0ms?
