GEOLOGY

Detailed explanation-1: -The magnetic properties of a substance can be determined by examining its electron configuration: If it has unpaired electrons, then the substance is paramagnetic and if all electrons are paired, the substance is then diamagnetic.

Detailed explanation-2: -If the crystalline structure of the atoms within a piece of metal is aligned so that all of the atoms are facing the same direction, that metal will be magnetic. In most materials, the atoms are not aligned into any sort of pattern. Only ferromagnetic materials are capable of being magnetized.

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: -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-5: -If the majority of electrons in the atom spins in the same direction, a strong magnetic field is produced. The direction of the electrons spin determines the direction of magnetic field. If the same number of electrons in the atom spins in opposite directions, the electron spins will cancels out.
