GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -A magnet is defined as. An object which is capable of producing magnetic field and attracting unlike poles and repelling like poles.

Detailed explanation-3: -Magnetism is a force that certain kinds of objects, which are called ‘magnetic’ objects, can exert on each other without physically touching. A magnetic object is surrounded by a magnetic ‘field’ that gets weaker as one moves further away from the object.

Detailed explanation-4: -Ferromagnetic: Material is strongly magnetized in presence of the magnetic field and retains its magnetic property even in absence of the external magnetic field. Examples: Iron, Nickel, Cobalt.

Detailed explanation-5: -Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges.
