A magnetic trap made up of a hollow, generally cylindrical body, having an open top, an inlet and an outlet for connecting to a flow line for liquid containing entrained removable magnetic material. There is a removable cover for the hollow body, a plate is supported on the cover, and elongated, spaced non-magnetic tubes are fixed to the cover. Elongated stacks of permanent magnets are attached to the plate and extend through the cover into the tubes. When magnetic material held to the tubes by the magnets is to be removed, the cover can be removed from the body, the magnetic stacks can be pulled out of the non-magnetic tubes with the plate, thereby removing the magnetic fields from the tubes so that the magnetic material held to the tubes falls off of the tubes, thereby cleaning the tubes.
