Abstract

PURPOSE:To simplify the processing of a movable iron core by providing an annular magnet and an exciting coil alternately and making magnetizing direction of the annular magnet and the exciting direction of the coil alternately opposing thereby preventing deterioration of the properties of the magnet. CONSTITUTION:The plurality of tubler coil 2 are placed inside a tube made of mangetic material. Annular magnets of the same shape as the coils are placed closely between the coils and at the both ends of the tube 1. Then the annular magnets are magnetized one by starrting from the one at the end in such manner that the inside and outside are magnetized in different porality. The movable iron core 4 of the length roughly equivalent to the combined thickness of one coil and two annular magnets is held slidablly by a sealed shaft 5 and bearings 6 which also act as caps at the both ends of the shaft. The magnetic field of each adjacent coil is in opposing direction. This maintains a constant flow of magnetic flux in the annular magnets preventing deterioration of the magnet and also simplifies the processing of the movable iron core.
