Define Magnetic force and Magnetic field

Description:A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. 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

They are all solids.

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
