Shopping tips
Due to their power, flat magnets are regularly applied in products that require strong holding power.
Typical temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value can increase.
Moreover, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet named MPL 200x30x30 / N38 and a lifting capacity of 183.51 kg with a weight of just 1350 grams, making it the excellent choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets ensure a larger contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often utilized in various 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 makes mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility creators a lot of flexibility in arranging them in devices, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, like cylindrical or spherical, may be a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, e.g. two north poles, act repelling on each other.
Due to these properties, 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. Additionally, the strength of a magnet depends on its dimensions and the materials used.
It’s worth noting 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. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe 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.
In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
- They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
- They show strong resistance to demagnetization from external magnetic fields,
- In other words, due to the glossy gold coating, the magnet obtains an aesthetic appearance,
- The outer field strength of the magnet shows advanced magnetic properties,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
- With the option for customized forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
- Significant impact in new technology industries – they are used in computer drives, electric drives, clinical machines as well as technologically developed systems,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of magnetic elements:
- They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture while also strengthens its overall strength,
- High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on size). 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,
- They rust in a damp environment. For outdoor use, we recommend using sealed magnets, such as those made of polymer,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing complex structures directly in the magnet,
- Potential hazard linked to microscopic shards may arise, in case of ingestion, which is significant in the context of child safety. Moreover, tiny components from these magnets might interfere with diagnostics when ingested,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Caution with Neodymium Magnets
Neodymium magnets are fragile and can easily crack as well as shatter.
Neodymium magnets are fragile as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal pieces 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.
If the joining of neodymium magnets is not controlled, then they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should hold them very firmly.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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.
It is important to maintain neodymium magnets out of reach from youngest children.
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.
Keep neodymium magnets as far away as possible 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.
Neodymium magnets are the most powerful magnets ever invented. Their power can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
If you have a nickel allergy, avoid contact with neodymium magnets.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
