A coil consisting of 88 windings of insulated wire is circular in shape with a radius r = 9.5 cm. The magnetic field is uniform throughout the coil and perpendicular to the coil's area, but it is changing with time. The magnitude of the magnetic field is initially 0.45 T and then changes at a constant rate until it has the same magnitude in the opposite direction. This change occurs over a time interval At =0.20 s. What is the magnitude of average emf induced in the coil during this time interval? E = If instead the magnetic field in the same coil remains constant at B = 0.45 T (in the same direction perpendicular to the coil's area, initially) and the coil itself is then rotated at a constant rate until it has inverted (gone through a rotation of 180°) during a time interval At = 0.10 s, what is the magnitude of the average emf induced in the coil during this time interval?
