History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]
HOW TO CALCULATE MAGNETIC FIELD OF MAGNETIC FILTER BAR? Powerful NdFeB Magnetic Filter Bar,Magnet Filters Rods is made from permanent magnets, stainless steel tubes and metal frames and is used to remove ferrous parts and tramp iron in the field of medicines, textiles, foods, grains, plastics,water,heating sulutionetc. The magnets bars can be strong Neodymium magnets, [...]
How to Select the Magnet Shapes A magnet is an object that exerts either an attractive force or a repulsive force on another object. Good examples of materials with strong magnetic properties are iron, mineral lodestone and certain types of steel. One popular type of magnets is the rare-earth magnet. Commonly called a neodymium magnet, [...]
Ferrite Magnets Overview Ceramic magnets are permanent magnets made up of a composite of iron oxide and barium/strontium carbonate. Through pressing and sintering ceramic magnets are made. These magnets are also made in different grades. They are widely used magnets with good magnetic strength and resistance to demagnetization. The color of ceramic magnet is charcoal [...]
Determine Strong Magnet Quality NdFeB magnets are popular word products in the market. At present, the demand in China's market is getting bigger and bigger, and the bidding is getting bigger and bigger. Many magnet manufacturers have better competitive advantages in the market. Will reduce the cost by using inferior raw materials. Therefore, when buying [...]
What are the difficulties when cutting ferrite magnets? A ferrite magnet is a metal oxide having ferromagnetism. In terms of electrical characteristics, ferrite magnets have much higher electrical resistivity than metal and alloy magnetic materials, and also have higher dielectric functions. The magnetic function of the ferrite magnet also exhibits a high magnetic permeability at [...]
Permanent magnet materials, also known as hard magnetic materials, are characterized by high anisotropy field, high coercivity, large hysteresis loop area, large magnetization field required for magnetization to saturation, and strong long-term retention after removal of external magnetic fields. Magnetic. In practice, the permanent magnet material operates in the second quadrant demagnetization portion of the [...]
See the B2B purchase platform for customers to buy ferrite magnets, Fortunately, we took a small order. Today, I saw someone buying a ferrite magnet on a procurement website. The information dissemination may not be transparent enough. As a result, many buyers have not found a suitable magnet factory. buy ferrite magnets I [...]
Discuss to Cooperation of Ceiling Fan Motor Magnet Mould with Taiwan Customer in MPCO Factory Because we are a custom-made magnet manufacturer, we often have customers directly to the company to inspect the factory or to negotiate mold opening of magnet. Yesterday, our colleague received a phone call from a Taiwanese customer, saying that three [...]
Purchasing Custom Ceiling Fan Motor Rotor Magnet The application of the magnetic rotor of ceiling fan motor, I think it can be seen from the popular area of the ceiling fan. The ceiling fan is one of the more life appliances we touch. The working principle is that the stator is a coil and is [...]

It can process and produce various powerful magnets, high temperature resistant magnets, irregular shaped magnets and ultra-fine precision magnets according to customers' drawings. Magnetic components such as permanent magnet chucks [...]
Sintered Ferrite magnet (Ceramic Magnets, Hard Ferrite Magnet) were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, Sintered Ferrite magnet (ceramic magnets, Hard ferrite magnet) have won wide acceptance due to their good [...]
