Question

A 20-turn circular coil of radius 4.20 cm and resistance 1.00 Ω 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 att = 5.40 s.
