What are Neodymium Magnets?
From its name they are magnets having neodymium as their core component. They are made of neodymium, boron, and iron. These materials have high magnetisation properties and are very strong.
In more technical terms, they are rare-earth magnets and are known to be one of the strongest magnets in existence.
Bulk neodymium magnets are versatile and well-preferred in the industry compared to ferrite or ceramic magnets. Some stand out features include their higher magnetic field and portability( easy to use and lightweight).
How are They Made?
Neodymium magnets are created through a process called sintering, which involves pressing powdered neodymium iron boron into a die and then heating it in a furnace. The heating process causes the individual grains of the material to adhere to one another, creating a strong bond between them.
This bond gives neodymium magnets their unique strength and durability. Neodymium magnets can also be formed using a process called injection molding, which involves melting the neodymium iron boron material and then injecting it into a mold. The molten material quickly solidifies and forms the desired shape. Injection molding allows for the production of complex shapes, as well as intricate patterns and designs.
What are They Used for?
Neodymium magnets fit into several uses across diverse industries. They are used in manufacturing processes to hold metal components or join them together.
Bulk neodymium magnets are used as refrigerator magnets, they also feature in electric motors used in vehicles, turbines, and machinery. Other applications include its usage in loudspeakers, headphones, smartphones, computer hard drive, medical devices and more.
The magnetic properties and durability of the neodymium magnet is responsible for its wide range of usage.
Are They Safe?
When it comes to magnets, safety is an important concern. Neodymium magnets are safe provided they are handled within safety measures and standards. As with any magnet, neodymium magnets should not be allowed to attract or “snap” together as they can pinch skin or fingers. Additionally, neodymium magnets are brittle and can break easily.
Fragments of neodymium magnets, like fragments from any magnet, can be dangerous if ingested, so it is important to keep them away from children and pets.
Neodymium magnets also have the potential to damage other items around them.
Electronics, such as hard drives and credit cards, can be damaged when placed too close to a neodymium magnet. Therefore, care should be taken when using these magnets near such items.
In general, neodymium magnets are safe to use when handled properly and kept away from children and pets. However, due to their powerful magnetic fields, extra caution should be taken when handling them.
Conclusion
Bulk neodymium magnets are safe if handled within safety standards and regulations. They offer good benefits and all you need is to follow safety rules regarding these magnets.
