Shopping tips
Thanks to their high strength, flat magnets are commonly applied in structures that need very strong attraction.
The standard 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, to improve their strength.
The magnet with the designation MPL 200x30x30 / N38 i.e. a magnetic strength 183.51 kg weighing a mere 1350 grams, making it the excellent choice for applications requiring a flat shape.
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often utilized in many devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: Their flat shape makes it easier mounting, especially when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits creators 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, reducing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet is dependent on the specific application and requirements. In certain cases, other shapes, like cylindrical or spherical, may be more appropriate.
Magnets have two main poles: north (N) and south (S), which attract each other when they are oppositely oriented. Similar poles, such as two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are commonly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its dimensions 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 once this temperature is exceeded, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe cards or medical equipment, like pacemakers. Therefore, it is important to avoid placing magnets near such devices.
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their stability, neodymium magnets are valued for these benefits:
- They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (according to literature),
- They show superior resistance to demagnetization from external magnetic fields,
- The use of a decorative nickel surface provides a smooth finish,
- Magnetic induction on the surface of these magnets is impressively powerful,
- Thanks to their high temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
- With the option for customized forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
- Wide application in new technology industries – they are used in data storage devices, electric motors, diagnostic apparatus along with other advanced devices,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time enhances its overall durability,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of plastic for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing threads directly in the magnet,
- Possible threat due to small fragments may arise, when consumed by mistake, which is crucial in the family environments. Additionally, tiny components from these devices may disrupt scanning when ingested,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Handle Neodymium Magnets Carefully
The magnet is coated with nickel. Therefore, exercise caution if you have an 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.
Keep neodymium magnets away from 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.
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 magnetic are extremely fragile, leading to their cracking.
Neodymium magnetic are delicate and will break if allowed to collide with each other, even from a distance of a few centimeters. 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.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
Magnets will crack or alternatively crumble with uncontrolled connecting to each other. You can't move them to each other. At a distance less than 10 cm you should hold them very firmly.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can destroy 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. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets should not be around children.
Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
People with pacemakers are advised to avoid neodymium magnets.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
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.
