Chapter 23: Question 5: 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 0.475 s to move it into the field. Randomized Variables d = 2.05 cm t = 0.475 s a) What average current is induced in the ring in A if its resistance is 0.0100 Ω? b) What average power is dissipated in mW? c) What magnetic field is induced at the center of the ring in T?
