he figure below shows a wire carrying a current I = 15.0 A to the right. Below the wire is a small metal washer with a radius of a = 0.250 cm. The washer, oriented vertically, is initially ouching the wire, and is then dropped from rest. The washer falls a distance h = 0.475 m before touching a table below. You may assume that the wire is very thin, and that the metal ring of he washer is thin compared to its radius. You may also assume the magnetic field is nearly constant over the area of the washer and equal to the magnetic field at the washer's center. (a) What is the magnitude of the average induced emf in the washer (in nV) over the time interval between its release and the moment it hits the table?

Let's take a current-carrying cable with a gradually narrowing cross-sectional area along the length of the wire so the wire turns into the shape of a very long, truncated cone. How does the drift speed (vd) vary along the length of the wire? It speeds up with the length or vd first increases and then goes down after it reaches to a critical value.or It slows down with the length of the cable or vd remains the same regardless the cross section of the cable.
