Chapter 27 – Magnetic Field and Magnetic Forces
2. Magnetic Field Electric field : 1) A distribution of electric charge at rest creates an electric field E in the surrounding space. 2) The electric field exerts a force F E = q E on any other charges in presence of that field.

Magnetic force | Definition, Formula, Examples, & Facts
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. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges.

Developments in the physical separation of iron ore: magnetic …
In magnetic separation, as the mass and the magnetic susceptibility of the particle are fixed, only the magnetic field intensity or gradient can be varied to change the magnetic force. This is why it is extremely important to create a magnetic field of high intensity and gradient for oxidized iron ores in order to achieve higher iron recovery.
