Abstract
A DC current electromagnet is provided developing a high pulling force with reduced current consumption. This electromagnet has the form of a cylindrical pot and comprises a mobile armature which slides along a yoke piece through a closure air gap --e, S--, whose reluctance is low with respect to the reluctance of the working air gap --E, s-- when this latter is open and substantially constant during movement.
