Tipos de imanes: Explorar los imanes y el magnetismo

¿Qué es un imán?

A imán is something that pulls some metals. This pull is called magnetismo. It’s like a magic trick, but it’s science! Magnets have a campo magnético. You can’t see it. But it’s there! The campo magnético has lines. These are líneas de campo magnético.

Magnets have two ends. They are called postes. One is the polo norte. The other is the polo sur. North and south like each other. They pull. North and north push away. So do south and south.

 Tipos de imanes

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

• Imanes permanentes: These are always magnets.
• Imanes temporales: These are magnets only sometimes.
• Electroimanes: These use power to be magnets.
• Imanes de ferrita
• Imanes de NdFeB
• Imanes de álnico

2.1 Permanent Magnets

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

Neodymium (NdFeB) Magnets

Estos son los más fuerte magnets. We make these! They are used in many things.

• Coches: Coches eléctricos use them. They help the wheels go!
• Energía eólica: Aerogeneradores use them. They make power from the wind. We make great magnets.
• Almacenamiento de datos. Hard disk drives (HDD) need magnets to work.
• Imanes de NdFeB se utilizan en resonancia magnética.
• Teléfonos: They are in your phone.

Imanes de NdFeB are the best! For very strong magnets, look at our Imanes de NdFeB personalizados.

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

Imanes de cobalto de samario (SmCo)

Se trata de fuerte. They can get very caliente.

• Aviones: They are used in planes.

Ferrite/Ceramic Magnets

These are not as fuerte. But they are cheap.

• Altavoces: They are in many altavoces.
• These magnets use magnetic stripes (cards).
• Fridges: They stick to your fridge.
• Máquinas de IRM.
• Juguetes: You probably have them.

Imanes de álnico

These are old. But they are good with calor.

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

2.2 Temporary Magnets

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

2.3 Electromagnets

Estos imanes use power. You can turn them on and off.

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

Cómo elegir el imán adecuado

3.1. Magnetic resonance angiography

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

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

• Energy product (BHmax: Cómo fuerte is it?

  Permeabilidad magnética is imporatn.

  3.2 What Do You Need?

• Coches: Coches eléctricos need strong magnets. NdFeB es bueno.

• Médico: IRM needs big magnets.
• Juguetes: Small, imanes flexibles son buenas.
• Magnetic flux leakage should be low.

Por qué los imanes de NdFeB son los mejores

Imanes de NdFeB are great! Here’s why.

• Superfuerte: Son los más fuerte.
• Pequeño: They can be very small. But still fuerte.
• resonancia magnéticais used for many things.
• Formas: We can make them in many shapes. Like blocks. Or discs.
• Magnetic damping is important for a smooth operation.
• Revestimiento: We can coat them. This stops rust. Learn about Grado magnético to make them easy to use.
• They show magnetoresistance
• Se utilizan en magnetic switches.

We made some Imanes de NdFeB that help, turbinas eólicas 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.
