Medical devices implanted inside the body are often powered using transcutaneous energy transfer (TET), a type of wireless charging using a pair of closely spaced coils. Ari emf is generated around a coil inside the body by varying the current through a nearby coil outside the body, producing a changing magnetic flux. Calculate the average induced emf (in v) if each 1107mm coil has a radius of 190 cm and the current in the external coil varies from its maximum value of 130 A to zero in oven x 10'5 s. (Hint: Recall from Topic 19 that the magnetic field at the center of the currentacarrying external coil is a : MOI. Assume this magnetic field is constant over the interior coil's area and oriented perpendicular to the internal coil.) ZR :V Need Help
