What are neodymium magnets actually?

Depending on the temperature, these devices can have varying magnetic strength. Generally, the higher the temperature, the weaker their performance. Therefore, when choosing a magnet for professional use, it's important to consider this aspect. For domestic use, a regular neodymium magnet is usually sufficient as they are one of the most popular magnets on the market. They typically work well at temperatures up to 80°C. If you need a magnet that can operate at temperatures up to 450°C, you can opt for alnico magnets, invented in Japan in 1931.

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.

Magnets usually lose their properties when they start to rust. That's why it's important to take preventive measures. Opt for products with a good, sealed casing to prevent water from entering, which can permanently damage your magnet. Additionally, if possible, avoid water or high humidity. If you want to use the magnet for retrieving objects from water, always thoroughly dry it and check its sealability afterward.

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.

The higher the density, the stronger the magnet! So, consider this aspect if you plan to use the device for lifting specific objects. For small magnets like fridge magnets, the density may be very low. However, if you want to use the product in industries or even in a home workshop, it's crucial to carefully consider this aspect. It's important to note that each manufacturer measures magnetic strength in their own way because it affects many factors. Therefore, before making a purchase, pay special attention to how the device's creator describes it. That should be your best reference.

If you want to use the device as a knife or tool holder, a long strip that you can easily attach to the wall will work well. This is an example of a device with a specific application. However, you can also use a neodymium magnet to lift heavy objects, such as car parts, in your workshop. In this case, a more convenient shape will usually be more suitable. You need to match the size and weight of the object to your needs because if it is too heavy, you won't be able to use it comfortably. So, pay special attention to this aspect, and if the manufacturer does not provide precise dimensions or weight, inquire or see the product before purchasing.

The handle of the magnet should be on the top, not on the side. Additionally, it's good if it comes with a strong rope. Only in this way can you ensure that when lifting the magnet along with an object, it adheres to it with the highest possible force. This allows for a much better grip. Furthermore, if you intend to lift particularly heavy objects using the magnet, pay attention to ensure that the device's casing is robustly constructed and will not fail during work. It can be extremely dangerous for both you and your surroundings.

Magnetism as a phenomenon has been known to humanity for thousands of years. It was recognized as early as ancient times, as evidenced by the Greek origin of the word. Its power was already harnessed in the 12th century in the form of a compass, invented by Alexander Neckam. This teacher and theologian described it in 1187 and was the first European to use this device for navigation.

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!

Neodymium magnets are a peculiar family of rare earth metals and their alloys that are specially prepared to attract ferromagnetic objects. Neodymium magnets are essentially pieces of metals exposed to a strong magnetic field, possessing their own magnetic induction. Among the commonly used magnets, strong neodymium magnets which are often referred to as permanent magnets or solid magnets due to their extremely strong magnetic field. They are currently the strongest magnets available on the market.

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 constituent 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 strong 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 on Earth. 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.

Due to their strong magnetic field, neodymium magnets have found wide application in both common usage and various industries. Depending on the type and shape of the magnet, strong neodymium magnets are used in different sectors. Neodymium magnets can be found in computer technology, household appliances, and textiles. The use of neodymium magnets depends primarily on the demand for magnets with a strong magnetic field.
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.

Various types of neodymium magnets with unconventional shapes, such as balls or magnetic toys like NeoCube, are dependent on specific requirements or applications in particular devices, etc.

The oval-shaped cylindrical neodymium magnets are a distinctive type of neodymium magnet. They are usually magnetized axially, which makes them suitable for various industrial sectors. Cylindrical neodymium magnets are typically constructed with an additional protective coating of nickel and copper, making them highly resistant to damage and posing no threat to human skin or the body.

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.

This type of neodymium magnets is usually coated with a protective nickel layer, which prevents corrosion, rusting, and the harmful effects of external factors. It also protects the skin and the human body from the harmful effects of the magnet's constituent elements. Strong ring neodymium magnets possess unique magnetic properties. They have a magnetization direction along the diameter, so the magnet has poles evenly distributed across half of the diameter. Hence, one half of the diameter has a North (N) pole, while the other half has a South (S) pole.

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.

Plate-shaped neodymium magnets find applications in various industries as well as in everyday use. The use of plate neodymium magnets has resulted in reducing the dimensions and weight of magnetic systems.

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.

The number of possible applications for neodymium magnets is so extensive that it is impossible to list them all. From plate neodymium magnets to magnetic holders and unique magnets such as NeoCube in the form of magnetic balls or magnetic toys, neodymium magnets constitute a highly powerful group of magnets. These products have found extensive applications in industries (magnetic holders), automotive sector for various types of oil cleaners (cylindrical magnets), model making for high-quality brushless motors for vehicles and model airplanes (plate magnets). Strong neodymium magnets are also used in the furniture industry for various closures and furniture fasteners, especially for glass cabinets. Magnets for fastening aprons, blouses, trousers, and other garments are also becoming increasingly popular. Particularly important are the magnets used in the production of medical garments (flat cylindrical and plate neodymium magnets).

Factors that can affect a magnet's strength include:

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.
