A Brief Discussion on the Difference between Strong Magnets and Ordinary Magnets

Strong magnets belong to the powder metallurgy category with high surface activity. Special attention should be paid during phosphating to avoid damaging the surface characteristics of strong magnets, otherwise the surface of the electroplated product will not be flat and smooth. The relevant formulas for electroplating hardware and electroplating magnets are different, but the electroplating process and equipment of magnet companies are the same. Magnet factories should pay special attention when selecting electroplating suppliers. The chamfer before electroplating should be done at a reasonable angle, as too small an angle is not easy to plate, and too large an angle can cause the product to be too small in size and not accepted by customers.The magnetic poles of both powerful and ordinary magnets will not change, but we can use technical means to charge the same magnet with many poles. The premise of the magnet company is even numbers, which means that a magnet can have several N po

Maintenance Techniques for Strong Magnet IFM Magnetic Sensors

1. High frequency characteristics. With the promotion of application fields, the working frequency of sensors is required to be higher and higher, including water meters, automotive electronics industry, and information recording industry.2. Low power consumption. Many fields require sensors to have extremely low power consumption, and powerful magnets can extend the lifespan of sensors. Applied in implanting magnetic biochips, compasses, and more into the body.3. Clean once a half month, and the benefit of cleaning is that it can ensure the temperature stability of the magnet factory. More application fields require increasingly harsh working environments for cutting magnets in sensors, which requires magnetic sensors to have good temperature stability. Industry applications include the automotive electronics industry.4. Controlling the timing of lucky work can achieve anti-interference. There is no evaluation of the usage environment of sensors in many fields of powerful magnets, whi

The application of magnets in maglev trains today

Magnetic levitation train is a high-speed maglev train system that uses contactless electromagnetic levitation, guidance, and drive systems. It can reach a speed of over 500 kilometers per hour, making it the fastest ground passenger transportation tool in the world today. It has advantages such as fast speed, strong climbing ability, low energy consumption, low noise during operation, safety and comfort, no fuel, less pollution, and low price. And it adopts an elevated approach, occupying very little arable land. Magnetic levitation trains mean that these trains use the basic principle of magnets to levitate on rails instead of old steel wheels and track trains. Magnetic levitation technology utilizes the electromagnetic force in the magnet to lift the entire train carriage, freeing it from unpleasant friction and unpleasant clanging sounds, achieving fast "flight" without contact with the ground and fuel.The maglev train is the most fundamental breakthrough in railway technology sinc

Where are irregular magnets mainly used?

1、 What is a heteromorphic magnet?Heteromorphic magnets, as the name suggests, are definitely irregular and unusual magnets, and some ordinary magnets can also be processed into heteromorphic magnets.2、 Where are irregular magnets mainly used?It is reported that special-shaped magnets are mainly used in electroacoustics, electrical appliances, motors, mobile phones, and other fields, and their applications are quite extensive, which may be useful in various industries.3、 What are the common irregular magnets?Common irregular magnets include concave convex magnets, horseshoe magnets, tile magnets, and some counterbore magnets.4、 How are irregular magnets produced?This depends on the specific shape. The material of the magnet is relatively brittle, so the processing procedures are quite complex. There are also many machines used, such as fully automatic slicing machines, wire cutting, forming grinders, centerless grinders, punching machines, and other machines.5、 What are the advantages
