What Are Neodymium Magnets?

Neodymium magnets, also known as NdFeB or Neo magnets, are the strongest type of permanent magnets, made from an alloy of neodymium, iron, and boron. 

They have become popular due to their powerful strength, consistent magnetization, and compact size. 

As a neodymium magnet supplier, Adams Magnetic Products offers a diverse range of these solutions, including discs, rings, and blocks, tailored to meet the needs of various industries. 

These powerful magnets are known for their exceptional strength and versatility, making them suitable for high-performance applications.

Frequently Asked Questions

Do neodymium magnets lose strength over time?

Yes, they do, but not significantly, especially when properly cared for. Neo magnets are among the most permanent magnets available. As long as they’re not overheated or physically damaged, they physically lose less than 1% of their magnetic strength over a 10-year period, a change so slight it’s barely measurable.

We do not recommend it. These magnets are very hard and brittle, making machining processes like cutting or drilling risky. The heat generated can demagnetize them, and the brittle material may chip or break. If shaping is needed, specialized processes like EDM (Electrical Discharge Machining) or diamond tooling are used, but only by experienced professionals.

Yes, stacking magnets does increase their lifting capacity, but not linearly. When two or more magnets are stacked, the combined strength increases, though real-world performance often falls short of the ideal, proportional expectations due to material and alignment factors.

Neodymium magnets are a subtype of rare earth magnets, but they aren’t the only kind. There are also samarium cobalt types, but neodymium variants are the most common and also the strongest permanent magnets available commercially.
