Countersunk Magnet Factory Introduces The Characteristics Of Magnets

Update:29 Dec 2020

Countersunk Magnet Factory introduced that a magnet is an object that can generate a magnetic field. It is a magnetic dipole that can attract ferromagnetic materials such as iron, nickel, cobalt, and other metals. The determination of the magnetic pole is to hang a magnet on a thin line. The magnetic pole pointing to the north is called the north or N pole, and the magnetic pole pointing to the south is the guide pole or S pole. (If you think of the earth as a large magnet, the earth’s magnetic north pole is currently the S pole, and the geomagnetic south pole is the N pole.) The magnets with different poles attract each other, and the same poles repel each other. The guide pole and the pointing north pole attract, the guide pole and the guide pole repel, and the pointing north pole and the pointing north pole repel.


Magnets are substances that can attract or repel each other. If small molecules inside an object can be arranged in the same direction, it will become a magnet. The composition is that the atomic structure of iron, cobalt, nickel, etc. is special. The atom itself has a magnetic moment, and the molecular arrangement of these minerals is generally chaotic. Magnetic regions cannot show magnetism if they interact with each other, but under the guidance of an external force (such as a magnetic field), the molecular arrangement tends to be the same, and it shows magnetism, which is commonly known as a magnet. Iron, cobalt, and nickel are the most commonly used magnetic substances. Basically, magnets are divided into permanent magnets and soft irons. Permanent magnets are coupled with strong magnetism to make the spin and electron angular momentum of the magnetic substance arranged in a fixed direction, while soft magnetism is Adding electric current (also a method of adding magnetic force) and so on, removing the soft iron will gradually lose its magnetism.
