What is the Disadvantage of a Neodymium Magnet?

Bad Things About Neodymium Magnets

Neodymium magnets are super strong! But they have some bad things too. We make these magnets. We want you to know all about them.

Neodymium Magnet

What are Neodymium Magnets?

They are magnets. They are made of neodymiumiron, and boron. That’s why they are called NdFeB magnets. They are very, very strong. They are used in many things like toys and computers.

1. They Can Break Easily

Neodymium magnets are brittle. This means they can break or chip. If you drop one, it might crack. About 25 out of 100 magnets might break when people use them.

  • Problem: They break!
  • Our Fix: We make our magnets extra strong. We test many to ensure strong magnets. Custom Neodymium Magnets

Like This: Cars use magnets. Some magnets in car parts broke. This was in Germany. It happened in 2019.

2. They Can Rust

Neodymium magnets can rust. This is like when metal gets orange and crumbly. Water makes them rust. Salt water is even worse!

  • Problem: They rust!
  • Our Fix: We put a special coat on our magnets. It’s like a raincoat. It stops the rust.Magnet Coating

More than 60 out of 100 magnets will rust if they get wet.

Like This: People used magnets in the sea in Norway, in the water. The magnets got rusty. They had to get new ones.

3. Heat Makes Them Weak

Neodymium magnets do not like heat. If they get too hot, they lose their power.

  • ProblemHeat makes them weak!
  • Our Fix: Some of our magnets can take more heat. They are called N42H magnets. We have many different Magnet Grade choices.

Like This: In Texas, it is very hot. Big wind machines (wind turbines) use magnets. Some magnets got too hot and stopped working in 2021.

If a magnet gets to 80 degrees (like a very hot day!), it loses some power. At 150 degrees (like an oven!), it loses a lot of power. . If looking to use a neodymium magnet in high trempature, try a N48M.

4. Other Magnets Can Make Them Weak

Strong magnets can make other magnets weaker. This is called de… demagnetization. It’s a big word! It means losing magnet power.

  • Problem: Other magnets can make them weak!
  • Our Fix: We make our magnets to keep their power. The ways we align the magnetic force helps.

Like This: Cars with electric motors use magnets. Some magnets in China got weak in 2020. The cars did not work as well.

5. They Can Be Dangerous

Neodymium magnets are very strong. They can pinch your fingers. They can even break bones! They can also mess up phones and computers.

  • Problem: They can hurt you!
  • Our Fix: We make our magnets with round edges, which helps. We also give you rules to be safe.

Like This: In America, some kids ate small magnets. They had to go to the hospital in 2022.

Half of all magnet hurts are from pinching.

6. They Can Be Bad for the Earth

Making neodymium magnets can be bad for the Earth. We get the neodymium from the ground. It can make the land dirty.

  • Problem: Making them can hurt the Earth!
  • Our Fix: We get our neodymium in a good way. We also reuse old magnets, also called recycling.

Like This: In China, there is a big hole in the ground. It is where they get neodymium. The land around it is not good.

Most of the neodymium comes from places that are not clean.

7. They Can Cost a Lot

Neodymium magnets can cost a lot of money. The price can go up and down.

  • Problem: They can be expensive!
  • Our Fix: We sell lots of magnets at a good price.

Like This: The price of neodymium went up a lot in 2022. It made things that use magnets cost more.

8. Sometimes, They Are Not the Right Size

Sometimes, you need a magnet that is a special shape or sizeNeodymium magnets might not come in that shape.

  • Problem: They might not be the right size!
  • Our Fix: We can make magnets in any shape you need! Check out our Customized NdFeB Magnets.

How to Pick a Good Neodymium Magnet

  1. Think: What will you use the magnet for? Will it get hot? Will it get wet?
  2. Pick: Choose a magnet with a coatNickel is goodEpoxy is also good.
  3. Ask: Make sure the magnet is safe. Look for RoHS and ISO 9001.
  4. Call to Action: We are very good at making neodymium magnets. Get your permanent magnet from a qualityNeodymium Magnets Factory.

Why Pick Us?

  • We are very smart at making magnets.
  • You can buy lots of magnets from us for less money.
  • We send magnets all over the world.

Other Questions

Can neodymium magnets get wet?

Yes, but they will rust. Make sure the coating on the magnetic sheet is good.

What happens if a neodymium magnet gets too hot?

It will get weaker.

Are your magnets safe for kids?

We have safe guidelines and quality packaging. But keep the magnets away from kids.
