Help me with the following.
A solenoid of radius 3.5 cm has 480 turns and a length of 25 cm. .(a). Find its. inductance IX Enter a number. ression for the inductance of a solenoid. mH (b) Find the rate at which current must change through it to produce an emf of 70 mV. (Enter the magnitude.) 5 X Use the relation between the induced emf across an inductor and the rate of change of the current through the inductor to find the rate of change required to produce the specified emf.

[-/1 Points] DETAILS SERCP11 20.2.P.012. MY NOTES ASK YOUR TEACHER PRACTICE ANO 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 changin 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- s. (Hint: Recall from Topic 19 that the magnetic field at the center of the current-carrying external c B = N.Po' . Assume this magnetic field is constant over the interior coil's area and oriented perpendicular to the internal coil.) 2R HINTStep by Step Solution
