A grate magnet apparatus comprising a frame defining an opening adapted to have material to be separated pass therethrough, a non-magnetic tube supported by the frame and extending across the opening, and an elongated magnetic member removably housed in the tube, whereby magnetic material is attracted to the tube when the magnetic member is housed in the tube and is released from the tube when the member is removed from the tube. The non-magnetic tubes and magnet members are connected both for joint movement to be withdrawn from the path of the flowing material and then for relative movement to release magnetic material from the non-magnetic tube.
