Mágnesek típusai: Mágnesek és mágnesesség felfedezése

Mi az a mágnes?

A mágnes is something that pulls some metals. This pull is called mágnesesség. It’s like a magic trick, but it’s science! Magnets have a mágneses mező. You can’t see it. But it’s there! The mágneses mező has lines. These are mágneses mezővonalak.

Magnets have two ends. They are called oszlopok. One is the északi pólus. The other is the déli pólus. North and south like each other. They pull. North and north push away. So do south and south.

 Mágnesek fajtái

There are many kinds of magnets. These are the main ones.

• Állandó mágnesek: These are always magnets.
• Ideiglenes mágnesek: These are magnets only sometimes.
• Elektromágnesek: These use power to be magnets.
• Ferrit mágnesek
• NdFeB mágnesek
• Alnico mágnesek

2.1 Permanent Magnets

These magnets are always “on.” They don’t stop being magnets. There are a few main types.

Neodymium (NdFeB) Magnets

Ezek a legerősebb magnets. We make these! They are used in many things.

• Autók: Elektromos autók use them. They help the wheels go!
• Szélenergia: Szélturbinák use them. They make power from the wind. We make great magnets.
• Adattárolás. Hard disk drives (HDD) need magnets to work.
• NdFeB mágnesek használják a mágneses rezonancia.
• Telefonok: They are in your phone.

NdFeB mágnesek are the best! For very strong magnets, look at our Testreszabott NdFeB mágnesek.

We like NdFeB a lot. We are good at making them. We even make Mágneses bevonat to make them last longer!

Szamárium-kobalt (SmCo) mágnesek

Ezek a következők erős. They can get very hot.

• Repülőgépek: They are used in planes.

Ferrite/Ceramic Magnets

These are not as erős. But they are cheap.

• Hangszórók: They are in many hangszórók.
• These magnets use magnetic stripes (cards).
• Fridges: They stick to your fridge.
• MRI gépek.
• Játékok: You probably have them.

Alnico mágnesek

These are old. But they are good with hő.

• Gitár hangszedők
• Érzékelők
• Music: They are used in some music things.

2.2 Temporary Magnets

Ezek a mágnesek are not always “on.” They only pull when something else is there. Like a metal that gets pulled.

2.3 Electromagnets

Ezek a mágnesek use power. You can turn them on and off.

• Big Cranes: They lift heavy things.
• MRI: They help doctors see inside you.

Hogyan válasszuk ki a megfelelő mágnest

3.1. Magnetic resonance angiography

It helps to know about magnet therapy. Here are the simple facts you need.

• Koercitás (Hc): How hard is it to stop being a magnet?
• Hőmérséklet stabilitás: Can it work when hot or cold?

• Energy product (BHmax: Hogyan erős is it?

  Mágneses permeabilitás is imporatn.

  3.2 What Do You Need?

• Autók: Elektromos autók need strong magnets. NdFeB jó.

• Orvosi: MRI needs big magnets.
• Játékok: Small, rugalmas mágnesek jó.
• Magnetic flux leakage should be low.

Miért az NdFeB mágnesek a legjobbak?

NdFeB mágnesek are great! Here’s why.

• Szuper erős: Ők a legerősebb.
• Kis: They can be very small. But still erős.
• mágneses rezonanciais used for many things.
• Formák: We can make them in many shapes. Like blocks. Or discs.
• Magnetic damping is important for a smooth operation.
• Bevonat: We can coat them. This stops rust. Learn about Mágneses fokozat to make them easy to use.
• They show magnetoresistance
• Ezeket a következőkben használják magnetic switches.

We made some NdFeB mágnesek that help, szélturbinák make more power!

Step-by-step instructions: How to buy ndfeb magnets

• Pick Specs.
• Ask for samples.
• Order lots.
• Magnetic circuit is a closed path.
