A neodymium magnet is a type of magnet that is made from neodymium (Nd), iron (Fe), and boron (B). It is one of the strongest magnets available in the market, with a magnetic strength up to 10 times greater than other magnets such as alnico or ferrite magnets. Neodymium magnets are widely used in various applications such as electric motors, speakers, combustion engines, and data processing systems. They are also used in medicine for the production of diagnostic devices like magnetic resonance imaging (MRI) machines.
Magnets are durable and highly useful. They can help in finding lost objects and serve as convenient holders in kitchens or workshops. However, to ensure their optimal performance, it is important to know what to look for. Learn about which magnet to choose to be satisfied with your purchase!

What aspects should you pay particular attention to before buying a neodymium magnet?
Operating temperature - Neodymium magnets are sensitive to high temperatures, so it's worth checking the permissible operating temperature of a specific magnet.
Coating - Neodymium magnets can be coated with special protective layers, so it's important to check whether a magnet is adequately protected against corrosion and other damage.
Magnetic strength - It's worth paying attention to the magnetic strength because the greater it is, the more efficient and durable the magnet will be.
Diameter - Some neodymium magnets can be very small and hard to notice, so it's important to consider their diameter to ensure they are adequately visible and robust.
Thickness - Neodymium magnets can have different thicknesses, so it's worth checking the thickness of a magnet to ensure it is strong and durable enough.
Surface - Neodymium magnets can have different surfaces, such as smooth, rough, or textured, so it's important to consider this feature to ensure the magnet
When considering a professional product, always carefully review the manufacturer's guidelines regarding the temperatures at which the magnet can be used. This will help you avoid disappointment. Also, note that the properties of the magnet usually improve when the temperature decreases, unless you exceed the maximum value specified by the manufacturer.
Avoid enclosures with leaky joints. Although they may cost slightly more, they provide proper protection for your magnet. Note that neodymium magnets are particularly prone to rusting. They are usually coated with a layer of nickel, but if you intend to use them underwater, consider a different type of device.
Therefore, the use of modern permanent magnets seems like a natural progression of technology, especially considering that such durable products help reduce environmental pollution, which has been steadily increasing due to human activities. Moreover, they are difficult to replace with anything else. Their durability and extraordinary strength are essential in certain industrial sectors. So, choose your device consciously, based on your own needs and knowledge about them, to select a product that will serve you well for many years. If you take care of it, it will be a one-time purchase!
A neodymium magnet is a magnet that typically has two magnetic poles - North (N) and South (S), also known as an en magnet. The main component of every neodymium magnet is the chemical element - neodymium. Neodymium magnets are formed by combining metals that are highly responsive to magnetic fields, namely neodymium, boron, and iron (Nd2Fe14B).
The production of strong neodymium magnets, also known as sintered neodymium magnets, involves pressing powdered materials using a very powerful magnetic field that affects all components of the magnet. The pressed neodymium magnet then undergoes a sintering process at a high temperature in a special vacuum furnace or in a specially created protective atmosphere. This process results in the neodymium magnet acquiring a very strong magnetic field, making it the strongest magnet in the world. Neodymium magnets are additionally coated with a protective layer to prevent corrosion and to mitigate the chemical activity of neodymium, such as a nickel, gold, epoxy, or other coating.
It is important to remember that neodymium magnets are susceptible to chipping and damage due to their structure. To increase the resilience of each magnet, additional metal alloy additives are used. This allows the production of neodymium magnets that are resistant to both mechanical damage and higher temperatures up to 230°C.
Why is this important? Because without the additional metal alloy additives that provide durability to the magnets at higher temperatures, above 80 degrees Celsius, the neodymium magnet loses its magnetic properties.
It is important to handle neodymium magnets with great care. Due to their strong magnetic induction, they can cause damage or immobilization of certain electronic devices and other objects.
Strong neodymium magnets can cause:
- injury to the user's body,
- damage to clothing,
- damage to electronic devices,
- damage to payment cards and phone cards,
- damage to data storage devices, including floppy disks, video cassettes, televisions, players, DVDs, hard drives, and memory cards.
Neodymium magnets allow the creation of various products that require the utilization of their strong magnetic induction, such as electric motors.
We produce several shapes of neodymium magnets:
- round neodymium magnets - cylindrical
- ring neodymium magnets
- plate neodymium magnets
- other custom shapes like stars, spheres, etc.
The main applications of strong cylindrical neodymium magnets include metal detectors, oil filters, toys, jewelry components, various types of latch handles for doors, cabinets, and other elements.
The smallest neodymium magnets are commonly used to create various refrigerator magnets.
The maximum operating temperature of this type of magnet is usually 80 degrees Celsius, unless it is reinforced with an additional protective coating. Ring neodymium magnets have a shape similar to cylinders with a hole in the middle, discs, or other similar shapes with a hole. They are ideally suited for applications where the best way to mount this type of magnet is with a screw or bolt.
Ring magnets are commonly used for door locks, window locks, magnetic locks, various types of fasteners, hanging cabinets, shelves, and other furniture.
In addition, magnets of this type can also be equipped with additional protective coatings, which allow them to operate at significantly higher temperatures, even up to 200 degrees Celsius. The magnetization of this shape type occurs along the smallest dimension. Strong plate neodymium magnets are mainly used as components in various types of electric motors in model making, for fasteners in cabinets, furniture locks, and other applications.
Small plate magnets are also used for refrigerator magnets and similar applications.

Temperature: High temperatures can weaken a magnet, while very low temperatures can temporarily reduce its magnetic strength.
Additional information: Magnets lose their magnetic strength as the temperature increases. Therefore, it is essential to avoid extreme temperatures around magnets.
Radiation: Prolonged exposure to radiation can impact the magnetic properties, leading to a decrease in the magnet's strength.
Additional information: Magnets used in environments with strong radiation, such as the nuclear industry, must be specially designed and protected.
Strong electrical currents in close proximity to the magnet: The flow of strong electrical currents near a magnet can affect its magnetic fields.
Additional information: In the case of permanent magnets, strong electrical currents may temporarily disturb their magnetic fields, but they typically do not have a long-lasting impact.
Other magnets in close proximity: If a magnet is in close contact with other magnets, it can influence their mutual magnetic fields.
Additional information: Magnets interact with each other, which can lead to an increase or decrease in their magnetic strength depending on their positioning and polarization.
Neodymium magnets are susceptible to corrosion in high-humidity environments unless they are protected by a protective coating.
Additional information: Neodymium magnets are very powerful, but they are also sensitive to moisture and corrosion. Therefore, they are often coated with a protective layer to extend their durability.
In addition, shock and vibration do not affect modern magnetic materials unless they are intense enough to physically damage the material. Additional information: Modern magnetic materials are more resistant to shocks and vibrations than older technologies, but there is still a possibility of material damage due to excessive mechanical forces. By using appropriate safeguards and designs, this risk can be minimized.
