<p>An electromagnet coil comprises a shell (1), a winding (5) and flanges. At least one portion of a flange (3) is fitted with a printed circuit board (6) with at least two connecting points (12, 13) joined to the ends of the winding and at least two junction terminals for connecting to a source. The assembly of the shell, winding and board are encased in a mould of insulating material (20) which is thermally conducting except at the regions (50, 28) intended to be accessible from the outside.</p> |
