An MRI technician moves his hand from a region of very low m

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 225 cm and it takes 0.45 s to move it into the field. d = 2.25 cm t = 0.45 s What average current is induced in the ring in A if its resistance is 0.0100 ohm? What average power is dissipated in mW? What magnetic field is induced at the center of the ring in T? B = 1.11 * 10^-5

r=d/2 =2.25/2 =1.125 cm

Magnetic field at the center of the ring is

B=u_oI/2r =(4pi*10^-7)*0.1767/2*0.01125

B=9.87*10^-6T
