A 200-turn circular coil of wire 21.6 cm in diameter acts as an antenna for FM radio at a frequency of 100 MHz. The magnetic field of the incoming electromagnetic wave has a maximum strength of 1.00×10^−12 T. (a) What power is incident on the coil area? W ( ± 1E-14 W) (b) What average emf is induced in the coil over one-fourth of a cycle (during which the magnetic field increases from 0 to its maximum value)? Assume that the magnetic field is perpendicular to the plane of the coil. mV ( ± 0.01 mV)
