<p>The electromagnet has an armature, a magnetic body made of magnetizable material, and a coil that is arranged in the body, where the body includes internal and external parts (1, 2) made of magnetizable material. The internal part is arranged in an opening of the external part. The parts are dimensioned in such a manner that a gap remains between the parts. The parts are in the shape of reciprocally opened cylinders, and are centered with each other. The external and/or the internal part have front sided through-holes (3), blind holes and/or internal threads. An independent claim is also included for a method for manufacturing electromagnets.</p> |
