Abstract: A magnetic inline filter is provided. A piston rod of a fluid cylinder is retracted to the top to locate an inner circumferential surface side magnet and an outer circumferential surface side magnet in filtration positions opposed to a space. In this state, a solenoid of a changeover valve is actuated to shut off a discharge port. A coolant is introduced into the space from an introduction port in the vicinity of the lower end of an outer pipe. Since a magnetic field in a radiation direction is intense, chips in the coolant are attracted to wall surfaces on both sides of the space and the coolant is filtrated. When the supply of the coolant is continued, the chips attracted to the wall surfaces are accumulated and bridged. As a result, since the coolant passes through gaps of the bridged chips, it is possible to perform precise filtration.
