GEOLOGY

Detailed explanation-1: -Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet.

Detailed explanation-2: -The force that a magnet exerts on certain materials, including other magnets, is called magnetic force. The force is exerted over a distance and includes forces of attraction and repulsion. North and south poles of two magnets attract each other, while two north poles or two south poles repel each other.

Detailed explanation-3: -This is called attraction. If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion. Opposite poles attract each other, but similar poles repel.

Detailed explanation-4: -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-5: -Coulomb law. According to this law, the Coulomb force is inversely proportional to the squared distance. This distance is taken between the Magnetic poles. This force may be a repulsive force which occurs between like poles (N–N, S–S) or may be an attractive force which acts between poles (N–S).
