Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their immense strength, neodymium magnets offer the following advantages:
- They retain their attractive force for nearly 10 years – the drop is just ~1% (based on simulations),
- They are highly resistant to demagnetization caused by external magnetic fields,
- Thanks to the shiny finish and silver coating, they have an elegant appearance,
- Magnetic induction on the surface of these magnets is impressively powerful,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- With the option for fine forming and precise design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
- Important function in new technology industries – they are utilized in computer drives, electric drives, healthcare devices or even high-tech tools,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which allows for use in small systems
Disadvantages of rare earth magnets:
- They are prone to breaking when subjected to a sudden 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 breakage , and at the same time strengthens its overall resistance,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on shape). 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 damp air can degrade. Therefore, for outdoor applications, we advise waterproof types made of rubber,
- Limited ability to create precision features in the magnet – the use of a magnetic holder is recommended,
- Possible threat related to magnet particles may arise, in case of ingestion, which is notable in the family environments. It should also be noted that minuscule fragments from these assemblies can complicate medical imaging after being swallowed,
- Due to the price of neodymium, their cost is above average,
Magnetic strength at its maximum – what it depends on?
The given lifting capacity of the magnet means the maximum lifting force, assessed in the best circumstances, namely:
- with the use of low-carbon steel plate acting as a magnetic yoke
- having a thickness of no less than 10 millimeters
- with a smooth surface
- in conditions of no clearance
- with vertical force applied
- in normal thermal conditions
Practical aspects of lifting capacity – factors
Practical lifting force is dependent on elements, by priority:
- 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 was determined using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance {between} the magnet and the plate lowers the load capacity.
Handle with Care: Neodymium Magnets
Neodymium magnets are highly delicate, they easily break as well as can become damaged.
Magnets made of neodymium are delicate as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If the joining of neodymium magnets is not under control, then they may crumble and also crack. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
The magnet coating contains nickel, so be cautious if you have a nickel 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 around children.
Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Intense magnetic 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.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Dust and powder from neodymium magnets are highly 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.
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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
