GEOLOGY

Detailed explanation-1: -In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic-but they are not yet magnets. To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet.

Detailed explanation-2: -How to tell if a substance is paramagnetic or diamagnetic. The magnetic form of a substance can be determined by examining its electron configuration: if it shows unpaired electrons, then the substance is paramagnetic; if all electrons are paired, the substance is diamagnetic.

Detailed explanation-3: -The magnetic moment is generated by the following two methods: The motion of Electric Charge. Spin Angular Momentum.

Detailed explanation-4: -Do all atoms have magnetic fields? The answer to this question is yes and no. All the electrons do produce a magnetic field as they spin and orbit the nucleus; however, in some atoms, two electrons spinning and orbiting in opposite directions pair up and the net magnetic moment of the atom is zero.

Detailed explanation-5: -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.
