An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner's 1.90 T field with his fingers pointing in the direction of the field. His wedding ring has a diameter of 2.21 cm, and it takes 0.330 s to move it into the field. What average magnetic field is induced at the center of the ring? (Enter the magnitude in teslas.)
