An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner’s 1.7 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 2.4 cm and assuming it takes 0.2 s to move it into the field.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
