GEOLOGY

Detailed explanation-1: -Magnetic domains are regions of matter where north and south poles of atoms line up in the same direction. Only certain materials, called ferromagnetic materials, can be magnetized . They include iron, cobalt, and nickel.

Detailed explanation-2: -When opposite poles of the magnets approach, they attract each other. Any north-south combination will pull them together. But when two like poles come together, they push each other apart. Two north poles will not stick together.

Detailed explanation-3: -All magnets have north and south poles. 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.

Detailed explanation-4: -Each domain behaves like a tiny magnet with a north and a south pole. In an unmagnetized piece of iron, these domains are arranged randomly. The magnetic effects of the domains cancel each other out, so this piece of iron is not a magnet. In a magnet, the domains are basically lined up in one direction.

Detailed explanation-5: -Groups of atoms join in such a way that their magnetic fields are all arranged in the same direction. The region in which magnetic fields of individual atoms are lined up in the same direction is called a magnetic domain.
