What is a Neodymium Magnet? Super Strong Magnets for Everyone!
Table of Contents
What Are Neodymium Magnets?
Neodymium magnets are very strong. They are also called NdFeB magnets. This is because they are made of:
- Neodymium (a kind of metal)
- Iron (you know iron!)
- Boron (another kind of thing)
These things are mixed together. Then they become a super strong magnet! They are much stronger than the magnets on your fridge.
We make these magnets! They are customized. That means we can make them any shape or size you need! Check out our Customized NdFeB Magnets.
How Strong are They?
They are very strong. We use numbers to show how strong they are. The numbers are called grades.
Here is a list!
- N35 is strong.
- N52 is the strongest!
- There is also N38, N40, N42,N45, N48, and N50.
The bigger the number, the stronger the magnet! Learn more about Magnet Grade. We can help you get the perfect grade.
Numbers also show how hot the magnet can get.
- M means it can get a little hot.
- H means it can get hotter.
- SH, UH, and EH mean they can get very hot!
- AH and BH are new grades.
We have all the grades! For example, N33M, N35M, N38M, N40M, N42M,N45M, N48M, N50M,N30H, N33H,N35H, N38H, N40H,N42H,N44H,N46H, N48H,N30SH, N33SH, N35SH, N38SH, N40SH, N42SH, N44SH, N46SH ,N28UH, N30UH,N33UH, N35UH, N38UH, N40UH,N28EH, N30EH, N33EH, N35EH, N38EH, N25AH, N28AH, N30AH, N25BH.
What are They Used For?
Neodymium magnets are used in lots of things!
| Where are they used? | What do they do? |
|---|---|
| Electric Cars | They make the motors go! |
| Wind Turbines | They help make power from the wind! |
| Phones | They make the speaker work! |
| Computers | They help store your pictures and games! |
| Hospitals | MRI machines use them to see inside your body! |
| Toys | They make fun magnetic games work! |
| Household Appliances | Used In things like washing machines |
| Power tools | Things like drills, and saws. |
| Industrial Equipment | Many types of machines use them. |
Wind turbines use lots of neodymium magnets. Each one can use 600 to 800 kilograms! ^4. We make special magnets for wind turbines.
Electric cars also use them. A car motor can use 2.5 kilograms of them. ^5
In Your Phone!
Your phone has a tiny speaker. That speaker uses a neodymium magnet. It makes the sound! We are experts in speaker magnets for all types of electroacoustic devices.
In Your Computer!
Your computer has a hard drive. It stores all your things. It uses these special magnets.
In the Hospital!
MRI machines! MRI is Magnetic Resonance Imaging. ^6 Big magnets help doctors see inside you! Neodymium magnets are great for this work.
How are They Made?
It’s like baking a cake, but much harder!
- We mix the Neodymium, Iron, and Boron.
- We press it very hard.
- We heat it very hot! This is called sintering.
- We make it the shape we need.
- We put a coating on it.
The coating is important! Neodymium magnets can get rusty. The coating stops that. We use coatings like:
- Nickel
- Copper
- Epoxy
- Gold
- Teflon, also known as PTFE Coating.
About 12% of magnets break because of bad coating. ^7 Our coatings are the best! Take a look at our selection and services at the Magnet Coating page.
Are They Safe?
Neodymium magnets are very strong. You need to be careful!
- Don’t put them near phones or computers if they are loose.
- Don’t let them snap together. They can break!
- Keep them away from small kids. They might swallow them.
Buying the Right Magnet
Picking the right magnet is important!
- Grade: Pick how strong you need it (N35 to N52).
- Coating: Pick the right coating for where it will be used.
- Shape and Size: What shape do you need? We can make any shape! We do customized ndfeb, magnetic modules, and magnetic systems.
We can help you! We are a neodymium magnet manufacturer. We make the best magnets. We can make them just for you!. This is called Custom Neodymium Magnets. We also make things like neodymium ball magnets, magnet fish, magnetic jewelry, magnetic sheets, and even gold magnetic items.

Where Does Neodymium Come From?
Neodymium is a rare earth element. That means it’s not easy to find. Most of it comes from China. It is used for Permanent Magnets. ^9 Some comes form other placers. We even create recycled ones!
What is NdFeB?
It stands for the following:
- Nd: Neodymium
- Fe: Iron
- B: Boron
