An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanners 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 0. 25 s to move into the field.
1. What average current is induced in the ring in A if its resistance is 0. 0100 ?
2. What average power is dissipated in mW?
3. What magnetic field is induced at the center of the ring in T?
