Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They virtually do not lose power, because even after ten years, the performance loss is only ~1% (in laboratory conditions),
- They are very resistant to demagnetization caused by external magnetic fields,
- Because of the brilliant layer of nickel, the component looks visually appealing,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- The ability for custom shaping or adjustment to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which amplifies their functionality across industries,
- Important function in cutting-edge sectors – they are utilized in HDDs, electric motors, clinical machines along with technologically developed systems,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are fragile when subjected to a strong impact. If the magnets are exposed to external force, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks while also reinforces its overall durability,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent loss 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. If exposed to rain, we recommend using waterproof magnets, such as those made of plastic,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing threads directly in the magnet,
- Potential hazard related to magnet particles may arise, if ingested accidentally, which is important in the context of child safety. It should also be noted that tiny components from these products might hinder health screening once in the system,
- In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,
Highest magnetic holding force – what it depends on?
The given strength of the magnet represents the optimal strength, determined in the best circumstances, that is:
- using a steel plate with low carbon content, serving as a magnetic circuit closure
- of a thickness of at least 10 mm
- with a smooth surface
- with no separation
- under perpendicular detachment force
- in normal thermal conditions
Lifting capacity in real conditions – factors
The lifting capacity of a magnet is influenced by in practice the following factors, ordered from most important to least significant:
- Air gap between the magnet and the plate, since 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.
* Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance {between} the magnet and the plate lowers the load capacity.
Handle Neodymium Magnets Carefully
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Keep neodymium magnets away from youngest children.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Do not bring neodymium magnets close to GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can 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 injuries.
Magnets will crack or crumble with uncontrolled connecting to each other. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
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 magnets can become demagnetized at high temperatures.
Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Magnets made of neodymium are extremely delicate, they easily fall apart and can crumble.
Neodymium magnetic are fragile and will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as 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.
