Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their mighty power, flat magnets are commonly used in structures that require strong holding power.
Typical temperature resistance of these magnets is 80°C, but with larger dimensions, this value rises.
In addition, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their durability.
The magnet named MPL 100x40x20 / N38 i.e. a magnetic strength 99.89 kg which weighs a mere 600.00 grams, making it the perfect choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often utilized in many devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: This form's flat shape makes mounting, particularly when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows designers greater flexibility in arranging them in structures, which is 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. It’s important to keep in mind that the optimal shape of the magnet depends on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be more appropriate.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Poles of the same kind, e.g. two north poles, repel each other.
Due to these properties, magnets are often used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.
It should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards or medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose power over time - after 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They possess very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which amplifies their universality in usage.
- Key role in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, medical equipment or very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They can break when subjected to a strong 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 at the same time increases its overall strength,
- They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Possible danger arising from small pieces of magnets are risky, when accidentally ingested, which is particularly important in the context of children's health. Furthermore, tiny parts of these magnets can be problematic in medical diagnosis when they are in the body.
Caution with Neodymium Magnets
It is essential to keep neodymium magnets out of reach from children.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays 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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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 TV, wallet, and computer HDD.
Strong 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can demagnetize at high temperatures.
Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
Neodymium magnets are not recommended for 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 are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can shock you.
To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If you have a finger between or alternatively on the path of attracting magnets, there may be a serious cut or even a fracture.
Neodymium magnets are especially delicate, resulting in damage.
Neodymium magnets are characterized by considerable fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
