An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner’s 1.7 T field with his fingers pointing in the direction of the field. (a) Find the average emf induced in his wedding ring, given its diameter is 2.4 cm and assuming it takes 0.2 s to move it into the field.
