9. (a) An MRI technician moves his hand from a region of
very low magnetic field strength into an MRI scanner's
2.00 T field with his fingers pointing in the direction of
the field. Find the average emfinduced in his wedding
ring, given its diameter is 2,2o em and assuming it takes
0.250 s to move it into the field, (b) Discuss whether this
current would significantly change the temperature of
the ring.
