Типы магнитов: Изучение магнитов и магнетизма

Что такое магнит?

A магнит is something that pulls some metals. This pull is called магнетизм. It’s like a magic trick, but it’s science! Magnets have a магнитное поле. You can’t see it. But it’s there! The магнитное поле has lines. These are силовые линии магнитного поля.

Magnets have two ends. They are called столбы. One is the северный полюс. The other is the южный полюс. North and south like each other. They pull. North and north push away. So do south and south.

 Виды магнитов

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

• Постоянные магниты: These are always magnets.
• Временные магниты: These are magnets only sometimes.
• Электромагниты: These use power to be magnets.
• Ферритовые магниты
• Магниты NdFeB
• Магниты Alnico

2.1 Permanent Magnets

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

Neodymium (NdFeB) Magnets

Это сильнейший magnets. We make these! They are used in many things.

• Автомобили: Электромобили use them. They help the wheels go!
• Энергия ветра: Ветряные турбины use them. They make power from the wind. We make great magnets.
• Хранение данных. Hard disk drives (HDD) need magnets to work.
• Магниты NdFeB используются в магнитный резонанс.
• Телефоны: They are in your phone.

Магниты NdFeB are the best! For very strong magnets, look at our Подгонянные магниты NdFeB.

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

Магниты из кобальта самария (SmCo)

Это сильный. They can get very горячая.

• Самолеты: They are used in planes.

Ferrite/Ceramic Magnets

These are not as сильный. But they are cheap.

• Динамики: They are in many колонки.
• These magnets use magnetic stripes (cards).
• Fridges: They stick to your fridge.
• Аппараты МРТ.
• Игрушки: You probably have them.

Магниты Alnico

These are old. But they are good with тепло.

• Гитарные звукосниматели
• Датчики
• Music: They are used in some music things.

2.2 Temporary Magnets

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

2.3 Electromagnets

Эти магниты use power. You can turn them on and off.

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

Как выбрать правильный магнит

3.1. Magnetic resonance angiography

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

• Коэрцитивная сила (Hc): How hard is it to stop being a magnet?
• Стабильность температуры: Can it work when hot or cold?

• Energy product (BHmax: Как сильный is it?

  Магнитная проницаемость is imporatn.

  3.2 What Do You Need?

• Автомобили: Электромобили need strong magnets. NdFeB это хорошо.

• Медицина: МРТ needs big magnets.
• Игрушки: Small, гибкие магниты хороши.
• Magnetic flux leakage should be low.

Почему магниты NdFeB являются лучшими

Магниты NdFeB are great! Here’s why.

• Суперсильный: Они сильнейший.
• Маленький: They can be very small. But still сильный.
• магнитный резонансis used for many things.
• Формы: We can make them in many shapes. Like blocks. Or discs.
• Magnetic damping is important for a smooth operation.
• Покрытие: We can coat them. This stops rust. Learn about Степень магнитности to make them easy to use.
• They show magnetoresistance
• Они используются в magnetic switches.

We made some Магниты NdFeB that help, ветряные турбины 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.
