Not secure-gauss. vaniercollege. qc. ca integrated concepts: an mri technician moves his hand from a region of very low magnetic field strength into an mri scanner's 2.04 t field with his fingers pointing in the direction of the field. a) find the average emf induced in his wedding ring, given its diameter is 2.17 cm and assuming it takes 0.255 s to move it into the ield. mv b) what current is induced in the ring if its resistance is 0.0101 ω? c) what average power is dissipated? mw d) what magnetic field is induced at the center of the ring? what are the directions of the induced magnetic field and current, respectively, relative to the mri's field? a. into mri, counterclockwise b. out of mri, counterclockwise c. into mri, clockwise d. out of mri, clockwise
