Abstract
A flux concentrator is disclosed for generating a strong magnetic field. An inductor is provided for generating a primary magnetic field which is weaker than the strong magnetic field. A concentrator body has a hollow interior for receiving material to be acted upon by the strong magnetic field. The body is located within the primary magnetic field and shields the primary magnetic field from the hollow interior. A flux concentrator device is positioned within the hollow interior and has a slot extending therethrough. The flux concentrator device is coupled to the primary field for generating the strong magnetic field within the slot. Structure is provided to vary the size of the slot while the strong magnetic field is being generated in the slot.
