GEOLOGY

Detailed explanation-1: -A grouping of atoms that have their magnetic fields lined up in the same direction is called a magnetic domain. The entire magnetic domain acts like a bar magnet with a north and a south pole. In a material that is not magnetized, the magnetic domains point in random directions.

Detailed explanation-2: -A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.

Detailed explanation-3: -The Domain theory of magnetism states that within a magnetic substance there are many domains (regions) of magnetic force each with a North and a South. These domains are not aligned in any particular way, resulting in little or no magnetic field around the substance.

Detailed explanation-4: -The domain theory states that inside a magnet there are small regions in which the magnetic direction of all the atoms are aligned in the same directions. These regions are known as domains. Within a domain, the aligment of the magnetic direction is the same.

Detailed explanation-5: -Groups of atoms with aligned magnetic poles are called magnetic domains. Each domain contains an enormous number of atoms, yet the domains are too small to be seen with the unaided eye.
