What are neodymium magnets (NdFeB)?
Neodymium magnets are powerful magnets made of an alloy of neodymium (Nd), iron (Fe) and boron (B). They are also called rare earth magnets. Depending on the size, a neodymium magnet can have different strengths. Neodymium magnets are already extremely powerful at a very small size. A single super magnet made of neodymium can carry 10, 50 or even 400 kg of weight. This results in a whole range of possible applications for these small strong magnets.
At GAUDER you can order strong neodymium magnets in various strengths, sizes and shapes. Learn more about our versatile range and the unique properties of powerful magnets as well as their use in industry, technology and everyday life below.
In addition to neodymium magnets, you can also purchase ferrite magnets in our online shop. These ceramic magnets differ from neodymium magnets mainly in their adhesive force and temperature resistance. Magnets made of ferrite can attach lighter objects to surfaces and are also fit to be used at very high or very low temperatures. Visually, the only difference is that ceramic magnets are not provided with an alloy.
What do the letters and numbers of neodymium magnets mean?
Have you ever wondered why neodymium magnets are sometimes characterized with the letter N, as well as different two-digit numbers? This type of categorization is done according to the maximum energy product, in terms of the power of magnetic flux per unit volume, and thus indicates the magnetic force of the neodymium magnet. The N stands for neodymium.
The higher the number after the N, the stronger the neodymium magnet, with N52 indicating the strongest magnet. Thus, the N value provides a good orientation when choosing a suitable magnet if the holding force has to play a role in the magnet’s application.
What can neodymium magnets be used for?
Their strong magnetic force makes rare earth magnets popular components of products and services in various areas of industry, technology and at home. Some items, such as computers or headphones, would not fulfill their functions without neodymium magnets inside them to make them work.
Powerful magnets made of neodymium are also used for example
- in the automotive industry for the construction of engines,
- in plastics technology,
- in computer technology for the construction of hard disks,
- audio technology or
- lighting systems.

With their versatile shape, strong magnetic hooks make it easier for you to organize your household. Our silver colored neodymium hook magnets can hold up to 3 kg of weight and thus ensure, for example, that you never lose your front door keys again - simply attach a magnetic hook to the wall and hang your keys on it.
Neodymium magnets as teaching aids for schools and universities
Rare earth magnets can be used to present scientific phenomena in a classroom in an informative and playful way. Especially for younger children, it is exciting to discover the magnetic field of neodymium magnets with the help of iron filings.
Our magnetic balls as well as our cube magnets are also perfect for attaching materials to magnetic surfaces such as blackboards or whiteboards. This allows you to focus on the essentials in class or lecture, while the relevant documents are visible to all.
In our online store you can buy handy and high-quality neodymium magnets that will greatly facilitate your organization at school or university and make your lessons visually intriguing.
Safety instructions for neodymium magnets
Due to the pronounced strength of neodymium magnets, there are special dangers which are not always obvious at first glance, but which must nevertheless be taken seriously. Even a single super magnet can cause damage to health.
Children in particular should not play with rare earth magnets unsupervised, as improper use can lead to serious injuries in the worst case if the magnets are swallowed. Therefore, it is recommended to pay attention to children around magnets. Furthermore, painful bruising or even broken bones can occur if the skin gets between two or more neodymium magnets.
It is also recommended to keep certain magnetic records on floppy disks or magnetic tapes away from neodymium magnets, since they may suffer irreparable damage and important data may be lost when coming in contact with powerful magnets. You can find further, more detailed information on safety instructions in our blog.
Neodymium magnets from GAUDER — Your advantages at a glance
Neodymium magnets (NdFeB) consist of neodymium (Nd), iron (Fe) and boron (B). Our magnets are coated with a nickel-copper alloy, creating brilliant shine and a smooth surface. Additionally, this also protects our magnets against oxidation and abrasion.
The small strong magnets have a very high holding force even at the smallest dimensions. They belong to the group of rare earth magnets, which means that their high magnetic remanence flux density, coercive field strength and energy density exceed those of comparable types of magnets available. They attract each other and thus can be extended and attached to metallic surfaces or objects as desired by stringing them together.
We offer neodymium magnets in a wide range of sizes and shapes. In our assortment you will find disc magnets, bar magnets, ring magnets, ball magnets, cube magnets and self-adhesive magnets.
Neodymium magnets are used in many areas such as industries, by hobbyists, in workshops or in the household. In several industries, rare earth magnets are used by PC and cell phone manufacturers, motor workshops for DC motors as well as for linear motors and in certain areas of development technology. They are built into hard drives to make them run faster, or amplify the performance of speakers and headphones. They are also used in rechargeable batteries, in plastics technology, in lighting systems and in model making. Magnets have been used in many professions for years.
