A piece of wire bent into a loop, as shown in Fig. 10.5,
Chapter 10, Problem 12P(choose chapter or problem)
A piece of wire bent into a loop, as shown in Fig. 10.5, carries a current that increases linearly with time:
\(I(t)=k t \quad(-\infty<t<\infty)\)
Calculate the retarded vector potential A at the center. Find the electric field at the center. Why does this (neutral) wire produce an electric field? (Why can’t you determine the magnetic field from this expression for A?)
