ABSTRACT. A coil intended for magnetisation of finely ground magnetite ores during secondary extraction of iron is considered. It is in the shape of a cylindrical ring and is strung on the pulp tube, which is made of non–magnetic and non–conductive material. The coil has known dimensions of the inner diameter and length, obtained for technological reasons. A direct current with a large alternating current component flows through the coil, formed by a diode half–wave rectifier circuit. A methodology is given for determining the electrical parameters of the winding at a given mains supply voltage, heat load and cooling conditions.
Keywords: magnetising coil, magnetic separation, heat load
