A moving charged particle produces an electric current and hence a magnetic fi eld. Suppose a positively charged particle passes by a circular current loop as sketched in Figure Q21.7, with the loop and the particle’s path lying in the same plane. Make a qualitative sketch of the current through the loop as a function of time. Be sure to indicate the time at which the particle is closest to the current loop.
