Analytical analysis of magnetically coupled multipole cylinders

An analytical analysis is presented for the magnetic coupling between separated, radially-polarized multipole cylinders. These cylinders function as a magnetic gear and a formula is derived for computing the torque developed by such gears. The theory applies to rare-earth materials such as NdFeB, and is demonstrated via simulation of a practical device.
