Due to their strength, flat magnets are frequently applied in products that need very strong attraction.
Most common temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value rises.
In addition, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their corrosion resistance.
The magnet labeled MPL 30x10x5 / N38 i.e. a magnetic strength 6.84 kg which weighs only 11.25 grams, making it the excellent choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a greater contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often used in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: Their flat shape makes it easier mounting, especially when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows designers greater flexibility in placing them in structures, which is more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, minimizing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet depends on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, are a better choice.
Magnets have two poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are regularly used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring strong magnetic fields. Additionally, 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, magnetic stripe cards or medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (in laboratory conditions),
- Their ability to resist magnetic interference from external fields is impressive,
- By applying a bright layer of silver, the element gains a modern look,
- They possess strong magnetic force measurable at the magnet’s surface,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which expands their functional possibilities,
- Wide application in cutting-edge sectors – they are used in HDDs, rotating machines, clinical machines or even high-tech tools,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,
Disadvantages of magnetic elements:
- They may fracture when subjected to a strong impact. If the magnets are exposed to external force, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and reinforces its overall strength,
- Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Magnets exposed to moisture can oxidize. Therefore, for outdoor applications, we recommend waterproof types made of coated materials,
- Limited ability to create complex details in the magnet – the use of a magnetic holder is recommended,
- Possible threat related to magnet particles may arise, when consumed by mistake, which is significant in the context of child safety. It should also be noted that miniature parts from these magnets can hinder health screening if inside the body,
- High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Safety Precautions
Neodymium magnets are the strongest magnets ever invented. Their power can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Magnets made of neodymium are characterized by being fragile, which can cause them to become damaged.
Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will crumble. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
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.
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 jump and also touch together within a radius of several to almost 10 cm from each other.
Neodymium magnets can become demagnetized at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
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.
Do not give neodymium magnets to 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.
Never bring neodymium magnets close to a phone and GPS.
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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Pay attention!
To raise awareness of why neodymium magnets are so dangerous, read the article titled How very dangerous are very strong neodymium magnets?.
