Abstract
Two parts of a roller bearing are separated by a gap and rotate in relation to one another, one of which carries a circuit through which a current passes. The circuit is rigidly connected to the rotating ring of the roller bearing and moves in front of a disk carried by the stationary ring on which an electromagnetic field probe is mounted.
