Due to their strength, flat magnets are commonly applied in structures that need exceptional adhesion.
Typical temperature resistance of these magnets is 80 °C, but with larger dimensions, this value rises.
Additionally, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their strength.
The magnet with the designation MPL 30x15x10 / N38 and a magnetic force 16.75 kg weighing just 33.75 grams, making it the ideal choice for applications requiring a flat shape.
Contact surface: Thanks 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 utilized in different devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: The flat form's flat shape makes it easier mounting, especially when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in arranging them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet may offer better stability, reducing the risk of shifting or rotating. However, it's important to note that the optimal shape of the magnet depends on the given use and requirements. In certain cases, other shapes, like 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, such as two north poles, repel each other.
Due to these properties, magnets are commonly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its size and the material it is made of.
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 once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They retain their magnetic properties for nearly ten years – the loss is just ~1% (based on simulations),
- They protect against demagnetization induced by surrounding magnetic fields very well,
- By applying a shiny layer of nickel, the element gains a clean look,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- With the right combination of materials, they reach significant thermal stability, enabling operation at or above 230°C (depending on the structure),
- With the option for customized forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
- Significant impact in new technology industries – they are used in data storage devices, electric motors, healthcare devices or even sophisticated instruments,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to external force, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and strengthens its overall durability,
- They lose field intensity at increased temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the geometry 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 advisable to use sealed magnets made of rubber for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing complex structures directly in the magnet,
- Potential hazard due to small fragments may arise, in case of ingestion, which is crucial in the protection of children. Moreover, minuscule fragments from these assemblies may disrupt scanning once in the system,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Safety Precautions
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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Magnetic 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.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnetic are fragile as well as can easily crack as well as get damaged.
Neodymium magnetic are extremely fragile, and by joining them in an uncontrolled manner, they will crack. 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.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets may crack or crumble with uncontrolled joining to each other. You can't approach them to each other. At a distance less than 10 cm you should have them very strongly.
Neodymium magnets can become demagnetized 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.
It is essential to maintain neodymium magnets away from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can surprise you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
