ある。[Problems to be Solved by the Invention] However, it is difficult to perform sufficient desorption by simply backwashing in a demagnetized state. In particular, with coolant fluid, oil adheres to the matrix inside the electromagnetic filter, so it is difficult to remove and clean it sufficiently unless a lipophilic solvent is used as the backwash fluid.
Such lipophilic solvents are expensive, often volatile, flammable, odorous, and difficult to handle.

Therefore, the particles adsorbed to the matrix inside the electromagnetic filter are quickly peeled off from the matrix surface.
It becomes suspended in the liquid. Therefore, when a new stock solution is introduced into the electromagnetic filter and the liquid that had been stagnant is pushed out, the desorbed particles are also discharged out of the electromagnetic filter.
