Arten von Magneten: Erforschung von Magneten und Magnetismus

Was ist ein Magnet?

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

Magnets have two ends. They are called Pfähle. One is the Nordpol. The other is the Südpol. North and south like each other. They pull. North and north push away. So do south and south.

 Arten von Magneten

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

• Dauermagnete: These are always magnets.
• Temporäre Magnete: These are magnets only sometimes.
• Elektromagnete: These use power to be magnets.
• Ferrit-Magnete
• NdFeB-Magnete
• Alnico-Magnete

2.1 Permanent Magnets

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

Neodymium (NdFeB) Magnets

Dies sind die stärkste magnets. We make these! They are used in many things.

• Autos: Elektroautos use them. They help the wheels go!
• Windkraft: Windkraftanlagen use them. They make power from the wind. We make great magnets.
• Datenspeicherung. Hard disk drives (HDD) need magnets to work.
• NdFeB-Magnete werden verwendet in Magnetresonanz.
• Telefone: They are in your phone.

NdFeB-Magnete are the best! For very strong magnets, look at our Kundenspezifische NdFeB-Magnete.

We like NdFeB a lot. We are good at making them. We even make Magnet-Beschichtung to make them last longer!

Samarium-Kobalt-Magnete (SmCo)

Diese sind stark. They can get very heiß.

• Flugzeuge: They are used in planes.

Ferrite/Ceramic Magnets

These are not as stark. But they are cheap.

• Redner: They are in many Lautsprecher.
• These magnets use magnetic stripes (cards).
• Fridges: They stick to your fridge.
• MRI-Geräte.
• Spielzeug: You probably have them.

Alnico-Magnete

These are old. But they are good with Wärme.

• Gitarren-Tonabnehmer
• Sensoren
• Music: They are used in some music things.

2.2 Temporary Magnets

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

2.3 Electromagnets

Diese Magnete use power. You can turn them on and off.

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

Wie man den richtigen Magneten auswählt

3.1. Magnetic resonance angiography

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

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

• Energy product (BHmax: Wie stark is it?

  Magnetische Permeabilität is imporatn.

  3.2 What Do You Need?

• Autos: Elektroautos need strong magnets. NdFeB ist gut.

• Medizinische: MRI needs big magnets.
• Spielzeug: Small, flexible Magnete sind gut.
• Magnetic flux leakage should be low.

Warum NdFeB-Magnete die besten sind

NdFeB-Magnete are great! Here’s why.

• Superstark: Sie sind die stärkste.
• Klein: They can be very small. But still stark.
• Magnetresonanzis used for many things.
• Formen: We can make them in many shapes. Like blocks. Or discs.
• Magnetic damping is important for a smooth operation.
• Beschichtung: We can coat them. This stops rust. Learn about Magnet Grad to make them easy to use.
• They show magnetoresistance
• Sie werden verwendet in magnetic switches.

We made some NdFeB-Magnete that help, Windkraftanlagen 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.
