A magnetic dipole antenna is used to detect an electromagnetic wave. The antenna is a coil of 65.0 turns with radius 5.00 cm. The EM wave has frequency 479 kHz, electric field amplitude 0.640 V/m, and magnetic field amplitude 1.70 × 10−9 T. Assuming it is aligned correctly, what is the amplitude of the induced emf in the coil? (Since the wavelength of this wave is much larger than 5.00 cm, it can be assumed that at any instant the fields are uniform within the coil.)

Turns of a coil N = 65 turns
Radius = 5.0 cm = m
EM wave frequency = f = 479 kHZ = Hz
Electric field amplitude = =0.640 V/m
Magnetic field amplitude = = T
