Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are regularly applied in devices that require exceptional adhesion.
Most common temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value rises.
Additionally, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their durability.
The magnet with the designation MPL 12x10x4 / N38 i.e. a magnetic strength 3.46 kg with a weight of just 3.60 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often applied in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in arranging them in structures, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet can offer better stability, minimizing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet depends on the given use and requirements. In some cases, other shapes, such as cylindrical or spherical, are more appropriate.
Magnets have two poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Similar poles, such as two north poles, repel each other.
Due to these properties, magnets are commonly used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.
It should be noted that high temperatures can weaken the magnet's effect. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, credit cards or electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They possess very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
- Significant importance in the industry of new technologies – find application in HDD drives, electric drive mechanisms, medical apparatus or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Potential hazard associated with microscopic parts of magnets are risky, in case of ingestion, which is crucial in the context of children's health. Additionally, small elements of these products have the potential to hinder the diagnostic process after entering the body.
Handle Neodymium Magnets with Caution
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets will crack or alternatively crumble with uncontrolled connecting to each other. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
The magnet coating is made of nickel, so be cautious if you have an allergy.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Neodymium magnets should not be in the vicinity children.
Remember that neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets can become demagnetized at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Neodymium magnets are the most powerful magnets ever created, and their strength can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Neodymium magnets are extremely delicate, they easily fall apart as well as can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
