Soorten magneten: Onderzoek naar magneten en magnetisme

Wat is een magneet?

A magneet is something that pulls some metals. This pull is called magnetisme. It’s like a magic trick, but it’s science! Magnets have a magnetisch veld. You can’t see it. But it’s there! The magnetisch veld has lines. These are magnetische veldlijnen.

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

 Soorten magneten

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

• Permanente magneten: These are always magnets.
• Tijdelijke magneten: These are magnets only sometimes.
• Elektromagneten: These use power to be magnets.
• Ferriet magneten
• NdFeB magneten
• Alnico magneten

2.1 Permanent Magnets

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

Neodymium (NdFeB) Magnets

Dit zijn de sterkste magnets. We make these! They are used in many things.

• Auto's: Elektrische auto's use them. They help the wheels go!
• Windenergie: Windturbines use them. They make power from the wind. We make great magnets.
• Gegevensopslag. Hard disk drives (HDD) need magnets to work.
• NdFeB magneten worden gebruikt in magnetische resonantie.
• Telefoons: They are in your phone.

NdFeB magneten are the best! For very strong magnets, look at our Aangepaste NdFeB-magneten.

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

Samarium kobalt (SmCo) magneten

Dit zijn sterk. They can get very heet.

• Vliegtuigen: They are used in planes.

Ferrite/Ceramic Magnets

These are not as sterk. But they are cheap.

• Luidsprekers: They are in many luidsprekers.
• These magnets use magnetic stripes (cards).
• Fridges: They stick to your fridge.
• MRI-apparaten.
• Speelgoed: You probably have them.

Alnico Magneten

These are old. But they are good with warmte.

• Guitar pickups
• Sensoren
• Music: They are used in some music things.

2.2 Temporary Magnets

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

2.3 Electromagnets

Deze magneten use power. You can turn them on and off.

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

De juiste magneet kiezen

3.1. Magnetic resonance angiography

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

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

• Energy product (BHmax: Hoe sterk is it?

  Magnetische permeabiliteit is imporatn.

  3.2 What Do You Need?

• Auto's: Elektrische auto's need strong magnets. NdFeB is goed.

• Medisch: MRI needs big magnets.
• Speelgoed: Small, flexibele magneten zijn goed.
• Magnetic flux leakage should be low.

Waarom NdFeB-magneten de beste zijn

NdFeB magneten are great! Here’s why.

• Super Sterk: Zij zijn de sterkste.
• Klein: They can be very small. But still sterk.
• magnetische resonantieis used for many things.
• Vormen: We can make them in many shapes. Like blocks. Or discs.
• Magnetic damping is important for a smooth operation.
• Coating: We can coat them. This stops rust. Learn about Magneetgraad to make them easy to use.
• They show magnetoresistance
• Ze worden gebruikt in magnetic switches.

We made some NdFeB magneten that help, windturbines 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.
