Physical properties of NdFeB
Shopping tips
Thanks to their mighty power, flat magnets are commonly applied in products that require strong holding power.
The standard temperature resistance of these magnets is 80 °C, but with larger dimensions, this value grows.
In addition, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their corrosion resistance.
The magnet with the designation MPL 10x5x1.5 / N38 and a lifting capacity of 0.84 kg with a weight of just 0.56 grams, making it the ideal choice for applications requiring a flat shape.
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 are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: The flat form's flat shape simplifies mounting, especially when it is necessary 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 other shapes.
Stability: In certain applications, the flat base of the flat magnet can provide better stability, reducing the risk of shifting or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, are more appropriate.
Magnets have two main poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, act repelling on each other.
Due to these properties, magnets are often used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength 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 should be noted 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. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards or electronic devices sensitive to magnetic fields. 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:
- Their power is maintained, and after around ten years, it drops only by ~1% (according to research),
- They remain magnetized despite exposure to strong external fields,
- By applying a shiny layer of gold, the element gains a sleek look,
- They possess strong magnetic force measurable at the magnet’s surface,
- With the right combination of materials, they reach increased thermal stability, enabling operation at or above 230°C (depending on the structure),
- The ability for custom shaping as well as customization to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Wide application in cutting-edge sectors – they are utilized in hard drives, electric motors, medical equipment and sophisticated instruments,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They can break when subjected to a strong impact. If the magnets are exposed to physical collisions, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage while also enhances its overall durability,
- High temperatures may significantly reduce the strength 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,
- Magnets exposed to humidity can corrode. Therefore, for outdoor applications, we recommend waterproof types made of rubber,
- Limited ability to create precision features in the magnet – the use of a magnetic holder is recommended,
- Potential hazard related to magnet particles may arise, especially if swallowed, which is important in the context of child safety. Moreover, minuscule fragments from these assemblies may complicate medical imaging 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
Precautions
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.
If joining of neodymium magnets is not under control, at that time they may crumble and also crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
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.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.
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.
Magnets made of neodymium are highly delicate, they easily fall apart and can crumble.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will break. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.
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 over 10 times more powerful than ferrite magnets (the ones in speakers), and their strength can shock 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.
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.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
