/ / 3.2.1.1 / / magnetic material type DIA (Diamagnetic materials) was a little and a negative (- 10-5) this kind of material is a soft magnet. Born in atoms with magnetic moment the result is zero. When exposed to a magnetic field outside the material will show weak magnetism. In the direction of magnetic field, according to the rules of the blades against the sample materials, including copper, gold, silver, bismuth, and beryllium.1.1 / / / / / / 1.1.1 3.2.1.2 magnetic material type parameters (Paramagnetic materials) were a little. A positivity (10-3-10-5) atoms of this kind of material has a magnetic moment results is not zero. But the heat will make the magnetic moment of each atom point randomly. The sum of all the magnetic moment is zero. When the external magnetic field to the material. Magnetic moment parallel to the direction of the magnetic field is arranged outside and show magnetism, for example the material such as aluminum,. Platinum and manganese/ / 3.2.1.3 / / magnetic material type ferro (Ferromagnetic materials) is a positive number is in the range of 50 - 100 000, show a more than other types of magnetic materials Due to the internal magnetic domains (Magnetic Domain), when the external magnetic field to the material. A magnetic field induced the increases. Samples of materials at room temperature, including iron, cobalt, nickel, and alloys of the material with ธาตุแร earth (Rare Earth) these.
