Magnet It's An Object That Can Produce A Magnetic Field

A magnet is an object that can produce a magnetic field, a magnetic dipole that attracts ferromagnetic materials such as iron, nickel, and cobalt. The magnetic poles are determined to hang a magnet in a thin line, pointing to the North's magnetic poles, which refer to the Arctic or N poles, pointing south to Antarctica or S pole. (If the earth is to be a big magnet, then the current Earth's geomagnetic North Pole is s pole, the geomagnetic Antarctic is N pole.) The magnet poles suck, and the poles repel. Refers to the Antarctic and refers to the Arctic phase suction, refers to the Antarctic and refers to the Antarctic repel, refers to the Arctic and refers to the Arctic repel.

Magnets can be divided into "permanent magnets" and "non permanent magnets". A permanent magnet can be a natural product, also known as a natural magnet, and can be made artificially (the strongest magnet is NdFeB magnets). Non-permanent magnets, such as electromagnets, only appear to be magnetic under certain conditions.

Magnet Manufacturing

Some substances can be rubbed into magnets, material is not iron, or steel, but not all steel can be made into magnets because they contain their substance and stainless steel cannot act as magnets.

Now let's make magnets, magnets and a screwdriver is the material you need, take a magnet to rub the metal part of the screwdriver, from one end to the other, they rub repeatedly, and they can create a magnetic screwdriver.


ND-FE-B magnets, samarium cobalt magnets, aluminum-nickel-cobalt magnets, ferrite magnet production process is also different. From the process of speaking, there are sintered NdFeB magnets and bonded NdFeB magnets, we mainly talk about sintered NdFeB magnets.


Ingredients → melting ingot → milling → pressure type → sintered tempering → magnetic testing → grinding → pin cutting → electroplating → finished products.

The ingredient is the foundation, the sintering tempering is the key.

NdFeB Magnet Production Tools: smelting furnace, jaw crusher, ball mill, airflow grinding, compacting machine, vacuum packaging machine, isostatic Press, sintering furnace, heat treatment vacuum furnace, magnetic performance tester, Gauss meter.

NdFeB Magnet Processing tools: A special slicer, wire cutting machine, flat mill, double-sided machine, punching machine, chamfering machine, electroplating equipment.

Most of the matter is made up of molecules, molecules are made up of atoms, and atoms are composed of atomic nuclei and electrons. Inside atoms, electrons rotate continuously and revolve around the nucleus. Both of these motions of electrons produce magnetism. However, in most of the materials, the direction of electronic motion is different, disordered, and the magnetic effect counteracts each other. Therefore, most substances do not exhibit magnetism under normal conditions.

Iron, cobalt, nickel or ferrite, and other ferromagnetic substances are different, its internal electron spin can be arranged spontaneously in a small range, forming a spontaneous magnetization zone, this spontaneous magnetization area called magnetic domain. ferromagnetic materials magnetized, the internal magnetic domain neat, the direction of the same arrangement, so that the magnetic strengthening, it constitutes a powerful magnet. The iron-absorbing process of the magnet is the magnetization of the iron block, the magnetic iron block and the magnet between the different polarity of attraction, the iron block firmly with the magnet "sticky" together. We say magnets are magnetic.
