Thanks to their mighty power, flat magnets are frequently used in devices that require very strong attraction.
The standard temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value rises.
In addition, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their durability.
The magnet named MPL 3x3x1 / N38 and a magnetic strength 0.24 kg which weighs a mere 0.07 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 is beneficial in applications requiring a stronger magnetic connection.
Technology applications: They 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: This form's flat shape makes mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility creators a lot of flexibility in placing 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 offer 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 project and requirements. In certain cases, other shapes, like cylindrical or spherical, are a better choice.
Magnets have two main poles: north (N) and south (S), which attract each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are often used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the material it is made of.
It should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. Every magnetic material has its Curie point, 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, credit cards and even medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They have stable power, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
- They remain magnetized despite exposure to magnetic surroundings,
- Because of the brilliant layer of gold, the component looks visually appealing,
- They have exceptional magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
- The ability for accurate shaping and customization to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
- Wide application in modern technologies – they find application in data storage devices, electromechanical systems, diagnostic apparatus along with other advanced devices,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to shocks, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from damage and additionally reinforces its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the form 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 wise to use sealed magnets made of plastic for outdoor use,
- Limited ability to create complex details in the magnet – the use of a housing is recommended,
- Potential hazard due to small fragments may arise, in case of ingestion, which is significant in the context of child safety. It should also be noted that tiny components from these products may disrupt scanning once in the system,
- Due to the price of neodymium, their cost is considerably higher,
Maximum magnetic pulling force – what it depends on?
The given lifting capacity of the magnet corresponds to the maximum lifting force, calculated in ideal conditions, specifically:
- with the use of low-carbon steel plate acting as a magnetic yoke
- having a thickness of no less than 10 millimeters
- with a refined outer layer
- with no separation
- under perpendicular detachment force
- at room temperature
Key elements affecting lifting force
In practice, the holding capacity of a magnet is conditioned by these factors, from crucial to less important:
- Air gap between the magnet and the plate, because even a very small distance (e.g. 0.5 mm) causes a drop in lifting force of up to 50%.
- Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
- Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
- Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
- Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
- Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.
* Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. In addition, even a slight gap {between} the magnet’s surface and the plate decreases the load capacity.
Be Cautious with Neodymium Magnets
If you have a nickel allergy, avoid contact with neodymium magnets.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium 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.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnetic are especially delicate, which leads to shattering.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Avoid bringing neodymium magnets close to a phone or GPS.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can become demagnetized at high temperatures.
Whilst 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.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Keep neodymium magnets far from 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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.
