A flat coil of wire is used with an LC-tuned circuit as a receiving antenna. The coil has a radius of 0.24 m and consists of 360 turns. The transmitted radio wave has a frequency of 1.2 MHz. The magnetic field of the wave is parallel to the normal to the coil and has a maximum value of 2.2 × 10-13 T. Using Faraday's law of electromagnetic induction and the fact that the magnetic field changes from zero to its maximum value in one-quarter of a wave period, find the magnitude of the average emf induced in the antenna during this time.
