Difference between mechanical force and magnetic force

Mechanical forces are distinguished from the four natural forces of electromagnetism, the strong nuclear force, the weak nuclear force, and gravity. While each of the four natural forces does not require a physical connection, mechanical forces must travel through a medium.

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
