The figure below shows a 117-turn square coil rotating about a vertical axis at at o = 1,220 rev/min. The length of a side of the coil is 20.0 cm. The horizontal component of the Earth's magnetic field at the coil's location is equal to 2.00 x 10-5 T. 20.0 cm |20.0 cm (a) What is the magnitude of the maximum emf (in mV) induced in the coil by the Earth's magnetic field?
