Problem

A flat coil of N=150N = 150 turns, each of area A=25 cm2A = 25\,\mathrm{cm^2}, is held at rest inside a large electromagnet. The magnetic field is uniform over the coil and perpendicular to its plane, and its magnitude is increased steadily at dB/dt=0.80 T s−1dB/dt = 0.80\,\mathrm{T\,s^{-1}}. Find the magnitude of the emf induced in the coil.
