53. A 30-turn circular coil of radius 1 m and resistance 1 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 = 0.1 t + 0.04 t2
, where B is in tesla and t is in second. Calculate the induced
emf in the coil at t = 5 s.
