Abstract

Lifting magnet comprises a magnetic plunger (15) with a control section (15a) having a geometric structure so that an air gap is adjusted and/or enlarged by sliding the magnetic plunger in the direction of the lifting end position. Preferred Features: The magnetic plunger has a reduced plunger diameter in the control section. The control section of the magnetic plunger is conical.
