His wedding ring has a diameter of 2.05 cm and it takes 0.375 s to move it into the field.


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 0.375 s to move it into the field. 


Randomized Variables 

d=2.05 cm

t= 0.375 s ?


Part (a) What average current is induced in the ring in A if its resistance is 0.0100Ω.

Part (b) What average power is dissipated in mW? 

Part (c) What magnetic field is induced at the center of the ring in T?
