SUMMARY
Rotating a bar magnet sideways within a coil does not produce an alternating current (AC) due to the cylindrical symmetry of a perfect magnetic dipole. The magnetic field remains unchanged when the dipole is rotated about its axis. However, moving a magnet through a coil in one direction and then reversing the direction does induce an AC current. The number of turns in the coil can influence the magnitude of the induced current, but the orientation of the magnet is critical in determining the type of current generated.
