Neodymium magnets – high attractive force
The first group consists of neodymium magnets, which are made from an alloy of neodymium, iron, and boron. They are characterized by very high magnetic force relative to their dimensions. These magnets are available in round and rectangular versions, and in various classes, such as N38 or N42, which indicate their strength. They can be coated with a layer of nickel, copper, or additional protection. They are used in structures requiring high holding forces, in motors, handles, sensors, and enclosure closures. They are also used in 3D printers, audio systems, construction toys, and modern electronic gadgets.
Ferrite magnets – durability and resistance to harsh conditions
The second group consists of ferrite magnets, which are made from iron oxides combined with barium or strontium carbonate. Compared to neodymium magnets, they have lower holding power but are more resistant to high temperatures and moisture. They can be used outdoors without the risk of corrosion.
Ferrite magnets are a good choice for applications where extreme force isn't required, but durability and stability are important. They come in cylindrical or plate shapes and are often used in speakers, electric motors, magnetic closures, as well as educational learning aids and simple DIY projects.
Differences between neodymium and ferrite magnets
Neodymium and ferrite magnets differ primarily in their composition, attractive force, and resistance to environmental conditions. Neodymium is significantly stronger, allowing it to support high loads while maintaining a small size. However, it is more susceptible to mechanical damage and corrosion, so it is often protected with protective coatings. Ferrite is less strong but cheaper to produce and resistant to moisture and varying temperatures.
The use of magnets in practice
In practice, magnets from this category can be used to secure components in the workshop, create door latches, in tool holders, or in experimental designs. In modeling and electronics, they allow for easy assembly and disassembly of parts, in mechanical systems they act as clutches or position sensors, and in creative DIY projects they can be a decorative element or interactive installation. When choosing a magnet, it's worth considering not only its shape and dimensions but also its material.
