Q42: A -turn square coil of side cm rotates about a verti- cal axis at rev/min as indicated in Figure P31.42. The horizontal component of the Earth’s magnetic field at the coil’s location is equal to T.
(a) Calculate the maxi- mum emf induced in the coil by this field.
(b) What is the orien- tation of the coil with respect to the magnetic field when the maximum emf occurs?
