いる。The filter element 1 is a perforated plate made of a magnetic material with a thickness of, for example, 50 μm and has a large number of holes with a diameter of, for example, 60 μm, and when it is magnetized, it attracts magnetic fine particles in micron units in the liquid or gas that passes through it. (For details, see the specification of Utility Model Registration No. 1665285). An electromagnetic coil 12 that magnetizes the filter element 1 is wound around the circumferential surface of a canister 6 made of a non-magnetic material, and when a current is passed through it, a cylindrical body that surrounds the electromagnetic coil 12 and lid plates above and below it are formed. Lines of magnetic force flow as shown by dotted arrows in a magnetic circuit composed of a frame 13 made of a magnetic material, a case head 4 made of a magnetic material, a filter element 1, and a canister bottom 5 made of a magnetic material,
The film element 1 is magnetized. Since there is no magnetic material between the case head 4 and the filter element 1 and between the filter element 1 and the canister bottom 5, the case head 4 and the canister bottom 5
Diffusion of magnetic lines of force occurs between the two and the magnetic field strength decreases. Therefore, the volumes of the case head 4 and the canister bottom 5 are formed to be large in order to prevent this decrease in magnetic field strength and to allow the lines of magnetic force to pass through the entire area of the filter element 1.
