Permanent magnet refers to a kind of, in the absence of the presence of an external magnetic field, can still have a certain magnetic presence of material objects. Permanent magnets in our daily life, as well as some of the industrial production in the application and for a wide range, not only can be used for some of the easier material processing, but also can be used as some of the magnetic material of electronic products. Next let us come to understand some of the role of permanent magnets, as well as some of its manufacturers price recommendations.
Permanent magnets
Permanent magnets, also known as hard magnets, are not easily demagnetized, and are not easily magnetized. And most of the materials used as magnet conductors and electromagnets are soft magnets. The polarity of permanent magnets does not change, while the polarity of soft magnets changes with the polarity of the applied magnetic field. They both attract ferrous objects and we call this property magnetism. Note that permanent magnets are not easily demagnetized, not never demagnetized. The polarity does not change. There are natural ones and man-made ones. Not much difference in nature, attracts ferrous objects.
Difference between permanent magnets and electromagnets
Similarities: both produce magnetic fields
Differences: electromagnets have a magnetic field only when they are energized; permanent magnets have a constant magnetic field. Electromagnets use weakly magnetic substances, permanent magnets use paramagnetic substances. The internal molecular arrangement of substances are generally by the existence of magnetic moment, the size of the magnetic moment by the internal structure of the substance to determine the use of this property in engineering applications made of electromagnets and permanent magnets.
