Shopping tips
Thanks to their high strength, flat magnets are regularly used in products that need very strong attraction.
The standard temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value rises.
Moreover, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their durability.
The magnet with the designation MPL 5x5x2 / N38 i.e. a magnetic force 0.79 kg with a weight of just 0.38 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Due 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 used in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: This form's flat shape makes it easier mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows designers greater flexibility in arranging them in devices, which is more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet can provide better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific application and requirements. In certain cases, other shapes, like cylindrical or spherical, may be a better choice.
Magnets have two main 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, act repelling on each other.
Thanks to this principle of operation, magnets are commonly 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 powerful magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the materials used.
It should be noted 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. Additionally, 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 exercise caution when using magnets.
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They do not lose their strength nearly 10 years – the loss of lifting capacity is only ~1% (based on measurements),
- They are very resistant to demagnetization caused by external magnetic sources,
- Because of the brilliant layer of silver, the component looks aesthetically refined,
- They possess intense magnetic force measurable at the magnet’s surface,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
- The ability for custom shaping or adjustment to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which amplifies their functionality across industries,
- Key role in cutting-edge sectors – they find application in computer drives, electromechanical systems, healthcare devices as well as other advanced devices,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to physical collisions, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage and additionally enhances its overall strength,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on height). 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 wet environment – during outdoor use, we recommend using waterproof magnets, such as those made of polymer,
- The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is risky,
- Potential hazard linked to microscopic shards may arise, if ingested accidentally, which is notable in the health of young users. It should also be noted that miniature parts from these products can hinder health screening once in the system,
- In cases of large-volume purchasing, neodymium magnet cost may be a barrier,
We Recommend Caution with Neodymium Magnets
Magnets made of neodymium are delicate and can easily crack as well as get damaged.
Neodymium magnetic are delicate as well as will crack 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 collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets should not be around youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets can demagnetize at high temperatures.
Whilst Neodymium magnets can demagnetize 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.
Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
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 is coated with nickel. Therefore, exercise caution if you have an allergy.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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 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.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Neodymium magnets generate 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 destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
