10.Will my neodymium magnets lose strength over time?
Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged,
neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment.
They won't even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time.
Magnetic rods, also known as bar magnets or cylindrical magnets, are essential components in a wide range of industries due to their unique magnetic properties and versatility.

Neodymium Magnets China Manufacturer Custom Neodymium Arc Shaped Magnets
Arc magnets are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, PM motors use permanent magnet materials to generate constant magnetic potential sources. Instead of electric excitation, permanent arc magnets have many advantages, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption.

A magnetic filter rack is an innovative and highly efficient device designed to separate ferromagnetic particles from fluids, playing a crucial role in various industrial and laboratory applications. Its functionality is based on the principle of magnetism, which allows it to attract and retain metal contaminants, ensuring the purity and quality of the filtered medium.
Structure and Working Principle
Typically constructed from durable materials such as stainless steel, a magnetic filter rack features powerful permanent magnets or electromagnets arranged in a strategic configuration. These magnets generate a strong magnetic field that captures ferrous particles, including iron, nickel, and cobalt fragments, as the fluid passes through the rack. The rack's design often includes multiple magnetic rods or cartridges, maximizing the surface area for particle capture. When fluid containing metallic impurities flows through the rack, the magnetic force pulls the particles towards the magnetic surfaces, effectively removing them from the stream.
Custom Neodymium Magnet Shapes Rare Earth Magnets China Manufacturer
In the design of high-speed permanent magnet motor, the materials currently used usually have high coercivity. This is mainly due to the relatively low temperature coefficient of materials with high coercivity, which is more conducive to ensuring high-speed permanent magnets. The temperature of the motor rotor is relatively more stable. At the same time, materials with high coercivity have higher temperature adaptability and are currently used in a wide range of applications with higher temperatures. In addition, materials with higher coercivity usually have relatively higher compression resistance and anti-interference strength, and the centrifugal force that can withstand is relatively higher.
