摘要： The invention relates to an electromagnet comprising a pole tube (104) and a coil (106) that encloses the pole tube and is displaceable along a longitudinal axis of the pole tube. A first front face of the coil rests against a first abutment (2) connected to a first end section of the pole tube. According to the invention, an elastic element (101) is arranged between a second front face of the coil and a second abutment (105) connected to a second end section of the pole tube, wherein said elastical element supports itself against the second abutment and pretensions the coil against the first abutment. In this way, a permanent and constantly tensioned attachment of the coil on the pole tube is ensured in the event of temperature fluctuations and even vibrations, which can be easily released even after a longer exposure to humidity.
