The rectangular magnets with a large length-width ratio are permanent bar magnets. The bar-shaped magnet is easy to break due to external pressure. Permanent magnet bars are mostly found in aluminium nickel cobalt and ferrite. Our rare earth neodymium bar magnets for sale can provide greater magnetic force, which are only used for heavy holding.
Rare earth bar magnets usually refer to neodymium magnet bars, which have far more magnetic properties than any other kind of bar magnet. The neodymium bar magnet has a suction weight of 640 times that of itself and has always been considered to be the strongest bar magnet in the world. Rare earth neodymium bar magnets for sale are usually magnetized through the thickness, they are the best magnet for holding. As a leading permanent magnet manufacturer in China, Beilun Meank has adhesive neodymium bar magnets and plastic-coated neodymium bar magnets for sale.

Working Temperature: Our neodymium bar magnets are offered with maximum working temperature rang from 80 to 230 Degrees Centigrade.
Coating: neodymium bar magnets are usually delivered with nickel, epoxy, rubber and plastic waterproof coating.
As one of the professional bar magnets suppliers in China, we provide quality neodymium bar magnets for sale at great prices. And neodymium sphere magnets bulk are also available. Custom bar magnets are also available. Feel free to contact for further info.
a. Chemical composition: Nd2Fe14B: neodymium bar magnets are fragile,hard and corrosive;
b. Medium temperature stability: neodymium bar magnet loss of -0.09 ~ -0.13% br/ ° C. For low Hcj neodymium bar magnets, its working stability is lower than 80 ° C, and for high Hcj neodymium bar magnets, its working stability is higher than 200 ° C;
c. Excellent strength value: maximum (BH) of neodymium bar magnets for sale is up to 52MGOe
1. Stable Magnetic Polarity
Bar magnets have clearly defined north and south poles, offering predictable magnetic behavior—critical for scientific research, motor components, and teaching environments.
2. Durable, Reliable Structure
With a rigid block shape, bar magnets provide:
Easy positioning
