Can Magnets Lose Their Magnetism? The magnetic field of permanent magnets is not so permanent. Materials that are known as permanent magnets consist of magnetic domains, where electrons are aligned in pairs within atoms. Magnetism is weakened as a result of damage to this alignment caused by heat and electromagnetic fields. Samarium-cobalt magnets lose nearly [...]
Electro Permanent Magnet (EPM) is the newest technology, featuring 95% energy saving and totally safety compared with traditional electromagnet method. Only needs power during MAG and DEMAG periods. During working, no power supply is required. Driven by magnetism, MPCO’s magnetic solutions encompass a wide range of industrial sectors, including magnetic lifting system, magnetic clamping system, [...]
Magnetic Core Characteristics and Applications Magnetic components have been used in several power electronic devices for decades. They are used in a wide range of applications. In order to implement the designed magnetic components, it is essential to have a good understanding of magnetic materials and associated technology. In the previous article, we learned about [...]
Custom Magnetic Assemblies Magnetic assemblies are made of permanent magnets and metal housings so the magnetic circuits are altered in order to get specific magnetic characteristics or increase the durability of the magnets. The permanent magnet used to make the magnetic assembly could be any kinds. The most common ones are neodymium magnets and ceramic [...]

MPCO Magnet Client Messages I have a 2006 Yamaha r1. And im looking for the magneto rotor that goes around the stator. I don't need the whole assembly just the basket with magnets I am looking for a 10 inch round magnetic milling chuck. I am putting it on a rotary table. Can you send [...]
How Does Temperature Affect Different Magnets? The relationship between magnetic strength and ambient temperature is somewhat complicated. If you are in need of a magnet, however, it is important for you to understand how temperatures affect the strength of different types of magnets before choosing a product. This will allow you to choose the magnet [...]
Working With Magnets in High or Low Temperatures The ambient temperature surrounding your magnets during work impact their strength significantly, but each magnetic material is different. Which magnet works best in your conditions? Temperature and magnetic strength have a turbulent relationship. Some applications require magnets in freezing conditions, while others work in searing heat. Some [...]
Different Types Of Speaker Magnets Speaker magnets come in all sort of different sizes and shapes, but the materials that they’re made of can really make a difference in the way the speaker sounds. Nowadays, all kinds of speakers have a permanent magnet fixed behind the centre of the speaker cone. It helps to interact [...]
How Are Alnico Magnets Made? Alnico magnet was successfully developed in the 1930s. It is composed of aluminum, nickel, cobalt, iron, and other trace metal elements. Thanks to their high coercivity and high Curie temperature, Alnico magnets are widely used in many industrial and consumer products, such as motors, electric guitar pickups, microphones, sensors, speakers, [...]
Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]
