Why is magnet called perManent Magnet? It is mainly to maintain its magnetic magnets for a long time, such as natural magnets and artificial magnets, general magnets commonly seen in daily life, also known as hard magnets, are not easy to get rid of magnetic, nor are it easy to be magnetized. If the permanent magnet heating exceeds the temperature of the gift or is located in an environment where the strength of the reverse high magnetic field, its magnetism will also be reduced or disappeared. In addition to permanent magnets in magnets, there are also electromagnets that need to be powered on.

Relief, also known as demagnetization, is a way to reduce or permanent magnets. The English name may be Gauss, a unit named self -named. Because of the phenomenon of magnetic stagnation, most of the magnetic fields cannot be reduced to zero; therefore, the magnetic field is generally introduced to a small known magnetic field, called offset. … Magnetic can be performed in many ways, including: heating to the temperature above the Curie.

Permanent magnet principle

Natural permanent magnets are also called natural magnets, and permanent magnets can also be made by manual (the strongest magnet is 钕 magnet). Unlimited magnetic internal magnetic molecules (molecular magnetology) are arranged irregularly. After the magnetization process, magnetic molecules will be arranged regularly. At this time, the N pole and S pole of the magnetic molecule will make the magnet in the same direction to make magnetism and become magnets. At the same time, there are the opposite poles and poles on the same magnet of the same magnet.

Permanent magnet production

First of all, there must be raw materials, the main raw materials are iron oxide, and then the raw materials are burned, and then sent to the ball mill for grinding process. The ball milling opportunities mix the raw materials and water beads and water at a certain speed to control the grain size of the raw material to a certain range of the range Inside. The temperature of the magnetic sintering processing process is about 1200 ° C. It is necessary to burn up and down 12HR. You cannot quickly advance it. Let the magnetic crystal change to the characteristics of the required features and the final processing angle. Crash lack of angle.

Permanent magnet magnetic force

Calculation formula for magnets absorption: magnet volume × density × 600 (multiple)
Magnet density: The density of N35 is about 7.5 grams/cubic centimeter. Mowing
Magnetic weight: volume × density (30mm × 15mm × 5mm) × 0.0075 = 16.875 grams
Magnet suction: 16.875 × 600 = 10125 grams

In addition to the distance from the distance, the time will also decline permanent magnet.
