FIELD: physics.
SUBSTANCE: electromagnetic device includes a permanent magnet (51a) which forms a magnetic field, particularly having the shape of a rod, a holder (51c) rigidly connected to the permanent magnet, having a holding head (51c') facing the permanent magnet for clamping the permanent magnet and a holding bolt (51c") fixed on the holding head, as well as a cup (51b) for the magnet, having a bottom (51b') and a wall (51b") deviating from the bottom. The holding head of the holder at least partially fits into a lead (51#) on the bottom, such that the outer contact surface of the holding head (C) and the inner contact surface of the lead (B) touch to form a force closure between the cup for the magnet and the holder. The electromagnetic device is particularly meant for use as a vibration converter and/or vibration-type sensor.
EFFECT: possibility of use at extreme operating temperatures, higher endurance limit and easy mounting.
