Vedclass · Answer

(A) Magnetism is a physical phenomenon produced by the motion of electric charge,resulting in attractive and repulsive forces between objects. It is a fundamental force of nature.$A$ magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials,such as iron,steel,nickel,cobalt,etc.,and attracts or repels other magnets.
