Question

You toss a conductive open ring of diameter d 3.25 cm up in the air. The ring is flipping around a horizontal axis at a rate of 5.75 flips per second. (One flip is a full rotation.) At your location, the earth's magnetic field is Be 40.5 HT. What is the maximum emf induced in the ring? Number click to edit

Answer 1

The maximum emf induced in the ring is max = (1)(40. 5x 10-6)(π(3.25×10-*)(5.75(27)) 4.86x10 V 4.86V
