GEOLOGY

Detailed explanation-1: -all of the above. Explanation for the correct answer: A magnetic force is a type of force that acts on all the objects that produce a magnetic field around it, Therefore, a magnetic force acts with a stationary magnet because a magnet always has a magnetic field around it.

Detailed explanation-2: -What is the magnetic force? The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.

Detailed explanation-3: -Mathematically, we can write magnetic force as: This force is termed as the Lorentz Force. It is the combination of the electric and magnetic force on a point charge due to electromagnetic fields.

Detailed explanation-4: -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.

Detailed explanation-5: -Magnetic Force can be defined as the attractive or repulsive force that is exerted between the poles of a magnet and electrically charged moving particles. Hence, it is a consequence of the electromagnetic forces.
