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.
Note : An MRI ( Magnetic resonance imaging) scanner applies a very strong magnetic field about 0.2 to 3T ,which aligns the proton spins .
It is basically a solution so attached handwritten content below
