A long straight, current-carrying wire passes through the center ofa circular coil. The wire is perpendicular to the plane of thecoil.
a) if the current in the wire is constant, is the induced emf inthe coil zero or nonzero? Explain
b) if the current in the wire increases, is the induced emf in thecoil zero or nonzero? Explain
c) does your answer to part b change if the wire no longer passesthrough the center of the coil but is still perpendicular to itsplane? Explain
