An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner's 2 T field with his fingers pointing in the direction of the field.
(a) Obtain the average emf induced in his wedding ring, given its diameter is 2.12 centimeter and assuming it takes 0.258 second to move it into the field.
mV
(b) If the resistance of the ring is 1.00 ohm, find how much heat will be transferred to the ring during this time?
mJ
