A flat coil of wire is used with an LC-tuned circuit as a receiving antenna. The coil has a radius of 0.15 mand consists of 450 turns. The transmittedradio wave has a frequency of 0.8 MHz. The magnetic field of the wave is parallel to the normal to the coiland has a maximum value of 2.0 10-13 T. Using Faraday's law of electromagnetic induction and the fact that themagnetic field changes from zero to its maximum value inone-quarter of a wave period, find the magnitude of the average emf induced in the antenna during this time.
