- The output disk/shaft does not touch the body. The gap in between is filled with a fine, dry stainless steel powder.
- The powder is free flowing, until a magnetic field is applied from the coil. The powder particles form chains along the magnetic field lines, linking the disk to the body.
- The torque is proportional to the magnetic field strength, and therefore to the applied D.C. input current.
