Question: 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. His wedding ring has a diameter of 2.2 cm and it takes .475 s to move it into the field.
(a) What is the average current induced in the ring in A if its resistance is 0.0100 ohms?
(b) What is average power dissipated in mW?
(c) What magnetic field is induced at the center of the ring in T?
