- To explain self-inductance, it is helpful to consider the specific example of a long solenoid, as shown in the figure. This solenoid has only one winding, and so the EMF induced by its changing current appears across the solenoid itself. This contrasts with mutual inductance, where this voltage appears across a second coil wound on the same cylinder as the first. Assume that the solenoid has radius R, length Z along the z axis, and is wound with nnn turns per unit length so that the total number of turns is equal to nZ. Assume that the solenoid is much longer than its radius. A. Suppose that the current varies with time, so that dI(t)/dt≠0. Find the electromotive force EMF induced across the entire solenoid due to the change in current through the entire solenoid. Express your answer in terms of dI(t)/dt, n, Z, and R. B.
