Shopping tips
Due to their power, flat magnets are regularly used in devices that need exceptional adhesion.
Typical temperature resistance of flat magnets is 80°C, but with larger dimensions, this value grows.
Additionally, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet named MPL 15x15x5 / N38 and a magnetic force 5.92 kg with a weight of a mere 8.44 grams, making it the excellent choice for projects needing a flat magnet.
Contact surface: Due 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: These are often applied in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: The flat form's flat shape simplifies mounting, especially when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits creators 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 may provide better stability, minimizing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet depends on the given use and requirements. In certain cases, other shapes, like 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, act repelling on each other.
Due to these properties, magnets are regularly used in electrical devices, such as 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 size and the materials used.
It should be noted that high temperatures can weaken the magnet's effect. The Curie temperature is specific to each type of magnet, meaning that once this temperature is exceeded, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards and even medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They remain magnetized despite exposure to strong external fields,
- Thanks to the polished finish and gold coating, they have an aesthetic appearance,
- The outer field strength of the magnet shows advanced magnetic properties,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- The ability for precise shaping or customization to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which amplifies their functionality across industries,
- Wide application in new technology industries – they are used in hard drives, rotating machines, medical equipment and technologically developed systems,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of magnetic elements:
- They may fracture when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage while also enhances its overall durability,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing holes directly in the magnet,
- Safety concern related to magnet particles may arise, if ingested accidentally, which is notable in the family environments. It should also be noted that tiny components from these assemblies can disrupt scanning when ingested,
- In cases of tight budgets, neodymium magnet cost is a challenge,
Handle Neodymium Magnets Carefully
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
Do not give neodymium magnets to children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets are especially delicate, which leads to their breakage.
Neodymium magnetic are delicate and will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a significant injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a severe pressure or even a fracture.
The magnet coating contains nickel, so be cautious if you have a nickel allergy.
Studies show a small percentage of people have allergies to certain metals, including 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.
Neodymium magnets can demagnetize 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 among the strongest magnets on Earth. The surprising force they generate between each other can surprise you.
To handle 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.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
