A plurality of magnetic bars are spaced around the core member. A sleeve member is moveable between an uphole position where the sleeve member circumscribes the plurality of magnetic bars, and a downhole position where the sleeve member is located downhole of a portion of the plurality of magnetic bars and can be a collection basket. The wellbore cleanout tool further has a permanent magnet.
