A circular coil of radius 8.0 cm and 20 turns is rotated about its vertical diameter with an angular speed of `50 rad s^-1` in a uniform horizontal magnetic field of magnitude `3.0xx10^-2` . Obtain themaximum and average emf induced in the coil. If the coil forms a closed loop of resistance `10 Omega` , calculate the maximum value of current in the coil. Calculate the average power loss due to Joule heating. Where does this power come from?
