Abstract (en)
[origin: EP0924719A2] Apparatus for generating a magnetic field comprises a plurality of bobbins 14 arranged in a predetermined configuration. Each bobbin carries first and second current carrying coils (20, 21). By appropriately energising the coils a magnetic field can be produced which can be switched between a first direction and a second direction. In another mode of operation the coils can be energised to produce a magnetic filed which rotates. <IMAGE>
