Abstract: The present invention relates to a magnet that comprises a body and a slide arranged to be movable relative to the body between a first and a second position. The movement of the slide is limited by a first and a second section of the body in such a manner that at the first position of the slide, the second pole piece is in contact with the first section, and at the second position of the slide, the second pole piece is in contact with the second section.

Abstract: The present invention provides a magnet, which comprises a body having a first and a second section, and a slide arranged to be movable relative to the body between a first and a second position. The slide comprises a permanent magnet, and a first and a second pole piece that are attached to opposite magnetic pole surfaces of the permanent magnet. The first section comprises a hole that opens into a first cavity of the body, the bottom of the first cavity being delimited at least partly by the second section. The slide is movably arranged in the hole so that the second pole piece is directed towards the bottom of the first cavity, wherein at the first position of the slide, magnetic flux generated by the permanent magnet is short-circuited by the first section, and at the second position of the slide, magnetic flux generated by the permanent magnet is directed through the first and the second section.

Abstract: The present invention relates to a magnet, which comprises a body and a slide that is movably arranged inside a cavity of the body. The slide that comprises a permanent magnet is moved relative to the body by transferring a medium into and out of the cavity. The invention also relates to a method for handling metal sheets.

Abstract: The present invention relates to a magnet, which comprises a body and a slide arranged to be movable relative to the body between a first and a second position. The slide comprises a permanent magnet, and a cylindrical first pole piece and a second pole piece, which are attached to opposite magnetic pole surfaces of the permanent magnet. The body comprises a first and a second section made of magnetic material and being separated from each other by a third section that is made of non-magnetic material. The first section comprises a cylindrical recess into which the slide is movably arranged so that, at the first position of the slide, the cylindrical first pole piece, the permanent magnet and at least part of the second pole piece are located inside the cylindrical recess, and at the second position of the slide, at least part of the cylindrical first pole piece is located inside the cylindrical recess and the second pole piece is located outside the cylindrical recess.
