Abstract

A magnetic coupling, comprising: a first member having a first array of magnetic field generating elements; a second member having a second array of magnetic field generating element, the first and second members being arranged for relative movement; wherein a fluid path extends at least partially through the first member to enable cooling of at least one of the magnetic field generating elements of the first array.
