Please answer part B & C

(9%) Problem 4: 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 2.05 cm and it takes 0.375 s to move it into the field. Randomized Variables d = 2.05 cm 1=0.375 s * 33% Part (a) What average current is induced in the ring in A if its resistance is 0.0100 $2? 1=4.1 * Incorrect!
