Abstract (en)
[origin: WO0030129A2] An electromagnet (10) having a core with a plurality of elongated channels (16), a bottom opening (34) to each channel, and a coil (14) made up of a plurality of lengths of electrically conductive wire extending through each channel. The core has a top wall (24) and a plurality of spaced parallel vertical side walls (26, 28) which define the channels. The bottom end of each vertical side has horizontal flanges (30) which form the poles of the magnet (10) and also define the openings (34) to the channels.
