GEOLOGY

Detailed explanation-1: -Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.

Detailed explanation-2: -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.

Detailed explanation-3: -Magnetic materials like cobalt, nickel and iron are always attracted by magnets. Magnets cannot repel them, as magnets can only repel other magnets because they have poles, and like poles repel each other.

Detailed explanation-4: -The force with which a magnet attracts objects like iron is called Magnetic force.

Detailed explanation-5: -Detecting a Magnet’s Repelling Force They are repelled by magnetic fields. Paramagnets have unpaired electrons to let charge flow and are, therefore, attracted to magnetic fields.
