H...A general purpose type of multipole magnet is described which provides some unique advantages. It produces a very uniform dipole field which can be rotated about the longitudinal axis of the magnet. Higher order multipoles can also be rotated and can be excited simultaneously without the use of independent coils. A magnet having octupole geometry was built and shown to verify the basic ideas.
