CPC:

Magnetically- actuated clutches; Control or electric circuits therefor (clutches with magnetisable particles F16D37/02; ) > with an electromagnet not rotating with a clutching member, i.e. without collecting rings > with axially movable clutching members > with flat friction surfaces, e.g. discs

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1990.
