MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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. An 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 14.0-turn coil has a radius of 1.40 cm and the current in the external coil varies from its maximum value of 10.5 A to zero in 7.25 x 10-6 s. (Hint: Recall from Topic 19 that the magnetic field at the center of the current-carrying external coil is B = /Pot. Assume this magnetic field is constant over the interior coil's area and oriented perpendicular to the internal coil.) HINT Need Help? Read It Show My Work (Optional) ?
