An inductor is built using a circular coil that is 0.50 m long, has a 10.0 cm radius, and consists of 30 closely wound turns of wire. (a) Calculate the self inductance of the coil. (b) What is the magnetic flux inside the coil when it carries a constant current of 3.80 A? (c) At what rate do we need to change the current to produce a 1.5 V EMF in the inductor? If we reduce the current to zero at a steady rate, how long of a time should we use for that?
