What are Permanent Magnets?
Imagine a magnet on your fridge. It holds up your drawings, right? That’s a permanent magnet! It’s always magnetic. It doesn’t need batteries or electricity. Super important to consumer electronics.
- Permanent magnets are special because their magnetic power stays on.
- They’re different from electromagnets, which need electricity to work.
These magnets are hidden inside lots of things you use every day. Permanent Magnets are super important.
Why are Magnets Important in Electronics?
Magnets help electronics do many cool things!
| What Magnets Do | How it Works | Example |
|---|---|---|
| Make things move | Magnets push and pull to make motors spin. | Toys that move! Wind Turbine! |
| Store information | Magnets help computers remember things. | Your computer’s games! Data Storage |
| Help you hear sounds | Magnets vibrate to make sound in speakers. | Music from your phone! Audio Equipment! speaker magnets! |
| Sense things | Magnets show direction, like in a compass. | Mobile Devices |
Electronics need magnets to:
- Be small.
- Be strong.
- Work for a long time.
NdFeB Magnets: The Best Magnets!
There are different kinds of magnets. NdFeB magnets are the strongest! Think of them as the superman of magnets! We are a NdFeB Magnets Factory.
- NdFeB stands for Neodymium, Iron, and Boron. These are the things they’re made of.
- A neodymium magnet is really strong!
- They have a lot of power in a small size.
- This is why they’re used in so many electronics. So many magnets in automotive.
- For the automobile industry, NdFeB for the automotive industry , we need magnets!
- NdFeB magnets applications are all over!
Why are NdFeB magnets so good?
| Feature | What it Means | Why it’s Good for Electronics |
|---|---|---|
| Strong | Can lift heavy things! | Makes motors and speakers powerful. |
| Small | Don’t take up much space. | Fits inside phones and computers. |
| Stays magnetic | Doesn’t lose its power easily. | Works for a long time without problems. |
| Good in heat | Can function inside of hot things. | Can work inside cars and hard drives |
We make Customized NdFeB Magnets! You tell us the shape and size, and we make it! We’ll even add Magnet Coating!
How NdFeB Magnets Help Your Stuff Work
Let’s look at some examples:
A. In Your Computer (Hard Disk Drive)
Your computer has a hard disk drive (HDD). It’s like a big memory box.
- The HDD has tiny magnets inside.
- These magnets store all your pictures, games, and homework.
- NdFeB magnets help the HDD work fast and store lots of stuff.
- 650 Million units shipped in 2023.
B. In Your Phone (Speaker and Motor)
Your phone uses NdFeB magnets in two important places:
- Speaker: The speaker makes sound. A magnet helps a thin paper move back and forth really fast. This makes the sound you hear!
- Vibration Motor: This is what makes your phone shake! A tiny NdFeB magnet spins around to make the vibration.
We make customized ndfeb for things like a speaker!
C. In Electric Cars
Electric cars are cool! They use big, strong NdFeB magnets in their motors.
- The magnets help the wheels turn without using gas.
- NdFeB magnets make the motors smaller and lighter.
- 90% of Electric Vehicles use these magnets.
D. In Wind Turbines
Wind turbines make electricity from the wind. They use giant NdFeB magnets!
- When the wind spins the turbine, it turns the magnets.
- This creates electricity to power your house!
- Need a magnet for wind? Or a magnet for wind turbine? We’ll make it.
E. In Hospitals (MRI Machines)
MRI machines help doctors see inside your body.
- They use very powerful magnets.
- NdFeB magnets can make MRI machines smaller and cheaper.
- NdFeB magnets cut cost by up to 25%!
F. In Your Toys!
Many cool toys use magnets.
- magnets make the toys move. Or if you like toys that stick together!
Making NdFeB Magnets
It’s not easy to make these super magnets!
- Mix: We mix neodymium, iron, and boron together.
- Heat: We heat the mix until it’s really, really hot! Almost like lava!
- Press: We squeeze the hot mix into the right shape.
- Cool: We let it cool down so it becomes hard.
- make magnetic We use a magnetic field to make the mixture magnetic
- Coat: We add a special coating to protect it, like a raincoat. Nickel Plating is popular! PTFE Coating and Teflon Coating are other options.
We can create Custom Neodymium Magnets.
Grades of NdFeB Magnets
NdFeB magnets come in different grades, like different flavors of ice cream!
- N35, N38, N40, N42, N45, N48, N50, N52: These are common grades. The higher the number, the stronger the magnet. N52 is super strong!
- We also provide Magnet Grades like N33M, N35M, N38M, N40M,N42M, N45M, N48M,and N50M.
- H, SH, UH, EH, AH : letters show how well the magnet works when it’s hot.
- Recycling is important so the magnets can be used again.
Shapes of NdFeB Magnets
Magnets can be made in many shapes:
- Discs (like coins)
- Blocks (like bricks)
- Rings (like donuts)
- ring magnets are also popular.
- Arcs (like pieces of a circle)
- Like neodymium ball magnets
- And many more! We can even do a magnetic sheet!
We make Customized Neodymium Magnets.
