Shopping tips
Thanks to their high strength, flat magnets are regularly used 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 usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their corrosion resistance.
The magnet labeled MPL 13x10x5 / N35H and a lifting capacity of 3.38 kg with a weight of only 4.88 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often utilized in various devices, such as sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: This form's flat shape simplifies 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 greater flexibility in arranging them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, minimizing the risk of shifting or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the given use and requirements. In some cases, other shapes, such as cylindrical or spherical, are a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. Similar poles, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are regularly used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its size 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 navigational instruments, magnetic stripe cards and even medical equipment, like pacemakers. Therefore, it is important to avoid placing magnets near such devices.
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- Their power is durable, and after around 10 years, it drops only by ~1% (theoretically),
- They protect against demagnetization induced by external electromagnetic environments very well,
- By applying a reflective layer of gold, the element gains a sleek look,
- The outer field strength of the magnet shows elevated magnetic properties,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- With the option for customized forming and targeted design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
- Key role in modern technologies – they are utilized in hard drives, electric motors, healthcare devices and sophisticated instruments,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to physical collisions, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and increases its overall durability,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent deterioration 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,
- Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of synthetic coating for outdoor use,
- The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is restricted,
- Potential hazard from tiny pieces may arise, in case of ingestion, which is notable in the context of child safety. It should also be noted that miniature parts from these assemblies might complicate medical imaging after being swallowed,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Handle Neodymium Magnets with Caution
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 injuries.
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 in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
Avoid bringing neodymium magnets close to a phone or GPS.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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. 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.
Neodymium magnets can demagnetize at high temperatures.
While 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.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets produce strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
It is important to maintain neodymium magnets out of reach from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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.
The magnet coating is made of nickel, so be cautious 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.
Neodymium magnets are known for their fragility, which can cause them to become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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 fragments can be propelled in various directions at high speed. Eye protection is recommended.
