Abstract
The electromagnet system has a yoke (1) and a round core 92) that has a cylindrical shaft and an outwardly expanded cone section (25) toward the fastening end. The core has its shaft plugged in advance into a round hole (13) of the yoke proceeding from the outside. The cone section (25) of the core also has a thread with which it is turned into the thread-free round hole (13) of the yoke (1) by being turned. In this way, the core can be exactly positioned and a good interference fit and a good magnetic coupling are achieved.
