Question: A 30-turn circular coil of radius 4.00 cm and resistance 1.00 is placed in a magnetic field directed perpendicular to the plane of the coil.

A 30-turn circular coil of radius 4.00 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 2 0.040 0t 2, where t is in seconds and B is in tesla. Calculate the induced emf in the coil at t = 5.00 s.
