Shopping tips
Due to their strength, flat magnets are regularly used in devices that require exceptional adhesion.
Typical temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value rises.
In addition, flat magnets commonly have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 10x10x4 / N38 i.e. a lifting capacity of 3.16 kg which weighs only 3 grams, making it the ideal choice for applications requiring a flat shape.
Contact surface: Due to their flat shape, flat magnets ensure a greater contact surface with other components, which is beneficial in applications needing 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 important for their operation.
Mounting: This form's flat shape simplifies mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits creators greater flexibility in arranging them in devices, which is more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, like cylindrical or spherical, are more appropriate.
Magnets have two main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are regularly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them ideal for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.
It’s worth noting that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. The Curie temperature is specific to each type of magnet, 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 and even electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose power over time. After approximately 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping and the ability to adapt to specific requirements – 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 HDD drives, electric motors, medical equipment or very modern machines.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- 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,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Potential hazard associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which is particularly important in the aspect of protecting young children. It's also worth noting that small elements of these devices have the potential to hinder the diagnostic process after entering the body.
Precautions with Neodymium Magnets
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.
Neodymium magnets can demagnetize at high temperatures.
Even though 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.
It is important to keep neodymium magnets out of reach from youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when attract. Depending on how huge the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Keep neodymium magnets away from GPS and smartphones.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnetic are extremely fragile, they easily fall apart and can crumble.
Neodymium magnets are highly fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnetic 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, small metal fragments can be dispersed in different directions.
Neodymium magnets are the strongest magnets ever invented. Their power can shock you.
