As described above, the conventional mounting structure requires a great deal of effort to assemble, and also causes the following problems. When the coil 3 is used in a lifting magnet, the coil 3 is housed in the yoke, but if there is not enough space between the yoke and the end face of the coil 3, the drawer copper plate 20 may not be placed. It becomes difficult. However, it is not preferable to pull out the drawer copper plate 3 from the lower surface side (adsorption surface side) of the lifting magnet. Therefore, the design of lifting magnets using this type of coil,
It was necessary to pay close attention to manufacturing and maintenance.
