What are NdFeB Magnets?

NdFeB magnets are the strongest kind of permanent magnet you can find. They are made of special stuff called neodymium, iron, and boron. That’s why they are called NdFeB! We at NdFeB Magnets Factory make lots of these! You can even get Customized NdFeB Magnets made just for you. These are not the same that are put on your refridgerator.

Can a Strong Magnet Hurt Things?

Sometimes! Big magnets can be tricky. Let’s see what they can do.

1. Old Stuff vs. New Stuff

• Old TVs and Computers: Remember old TVs with big backs? Those are called CRT screens. A strong magnet can make the colors go funny. Old computers used something called floppy disks. Magnets can erase them!
• New Phones and Computers: New phones, like your mom’s iPhone, are safe! They use something called SSD. That’s like a tiny flash drive. Magnets can’t erase them easily. A report shows they won’t hurt an phone. New computers use SSDs too!

Here’s a table to show what’s safe and what’s not:

2. Hard Drives (HDDs)

These store your data with powerful magnetic fields.

• Hard Drives are like record players. They have spinning parts inside. A very strong magnet, very close, can mess them up.
• One test, the source showed that you need a magnet with 450 pounds of pulling power to hurt a hard drive. That’s a very big magnet! Most small house magnets won’t that.

3. Special Things

• Pacemakers: These help people’s hearts beat right. Strong magnets can mess them up. Keep magnets at least 6 inches away! These are medical devices.
• MRI Machines: These are giant magnets doctors use to take pictures inside your body. They are super strong! They have special rules.
• If you are using magnets at work with industrial robots, there are also rules.

4. Magnets in the house.

• The magnets on your fridge are safe. They are not strong enough to hurt most things. They won’t even hurt the tv screen. They are not permanent magnets.
• Magets wont effect OLED screens, and do not cause static electricity.

5. Cases with strong magnets

• Magnets in magnetic phoen cases and magnetic phone mounts are safe for your devices, because today’s electronics use flash memory.
• magnetic phont holders are also safe.

How to Be Safe with Strong Magnets

• Keep them away from old stuff: Like floppy disks and old TVs.
• Don’t put them near hard drives (HDDs): Keep strong magnets away from computers with hard drives.
• Be careful around medical things: Like pacemakers.
• Use a Faraday Cage if you use sensative electronics.
• Don’t let little kids play with strong magnets: They might swallow them! That’s very bad!

What We Do at NdFeB Magnets Factory

We make sure our NdFeB magnets are safe!

• We follow the rules: We have special papers that say our magnets are good.
• We make many types, using a complex magnetic field measurment tool! You can get Magnet Coating to make them last longer!
• We rate our magnets by Magnet Grade.

More Fun Facts About Magnets!

• Magnets can make things float! This is called magnetic levitation.
• Some trains use magnets to go super fast! They are called Maglev trains.
• Magnets are used in lots of things! Speakers, headphones, motors, and even toys!
• Magnets can help find things under the water! that’s called using a magnet fish.

Using magnets safely, is important.

Magnets and other technology

• Magnets will not damage your smartwatch.
• They will not damage Airpods. Magnets can be used for wireless charging.
• Big magnets can mess up a compass. If you have a phone with a compass, like an Iphone, it can get confused.
• A stylus pen uses a magnet, but it will nto damage things. We offer these magnets.
• You can order magnets for electroacoustic devices(speaker magnet) and speaker)).

Magnets and Power

• Magnets help make power.
• Eddy currents and corrosion can happen, but we use a special coating to protect our magnets.
• Some new vehicles use magnets and use RFID tag, but strong magnets will not demagnetize.
• Magnets are great helpers in the green new world.

Magnets in Cars and Planes!

Magnets are super important in cars and planes! They help make things work.

In Cars (Automotive)

• Electric Cars (EVs): These cars use big magnets in their motors. The magnets help the wheels turn! We make NdFeB for the automotive industry.
• Hybrid Cars: These cars use both gas and electricity. They also use magnets!
• Regular Cars: Even cars that only use gas have magnets. They help with things like the speakers and sensors.
• Tesla uses magnets!
• Magnets are even important in powertrain systems and automotive manufacturing.

In Planes (Aerospace)

• Planes use magnets in their engines.
• Magnets are getting used more for electric electric propulsion systems.
• Magnets help make the plane go! They are very strong and light.
• Magnets also help with things like the doors and seats.

Keeping Things Safe

• It’s important to use the right kind of magnet. We make special magnets that are safe for cars and planes.
• We test our magnets to make sure they are strong and won’t break.

Magnets All Around Us!

• Magnets are in lots of things we use every day.
• They are in your phone, your computer, and even your toys!
• It’s very rare that magnets would cause a short circuit.

Magnets in Wind Turbines

Wind turbines use big magnets to turn wind into electricity! It’s like a giant fan, but instead of making wind, it uses wind to make power.

How They Work

1. Wind blows and makes the big blades of the turbine spin.
2. The spinning blades turn a shaft inside.
3. The shaft is connected to a generator.
4. The generator has big magnets and coils of wire.
5. When the magnets move past the coils, it makes electricity! We make magnet for wind turbine!

Why Magnets are Great for Wind Turbines

• Strong Magnets: NdFeB magnets are super strong. This means they can make lots of electricity.
• Long Lasting: Our magnets don’t lose their power easily. They last a long time!
• Efficient: Magnets help make wind turbines work better. They help make more power from the same amount of wind.

We make the magnets for wind power.

We make special magnets that are just right for wind turbines! We can make a:

• neodymium magnet or
• motor magnet

Magnets in Other Things

Magnets are not just in wind turbines. They are in lots of other things too!

• Motors: Many motors use magnets to make things move.
• Generators: Generators use magnets to make electricity.
• Speakers: Speakers use magnets to make sound.
• Toys: Some toys use magnets to make them stick together or move.
