An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner's 1.60 T field with his fingers pointing in the direction of the field. His wedding ring has a diameter of 2.15 cm, and it takes 0.380 s to move it into the field.

(a) What average current is induced in the ring if its resistance is 0.0100 Ω? (Enter the magnitude in amperes.)

_________A

(b) What average power is dissipated (in W)?

_________W

(c) What average magnetic field is induced at the center of the ring? (Enter the magnitude in teslas.)

__________T

(d) What is the direction of this induced magnetic field relative to the MRI's field?

A. parallel

B. antiparallel

C. The magnitude is zero.
