Advantages and disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- Their strength is durable, and after around 10 years, it drops only by ~1% (according to research),
- They remain magnetized despite exposure to strong external fields,
- In other words, due to the shiny silver coating, the magnet obtains an stylish appearance,
- They possess strong magnetic force measurable at the magnet’s surface,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to build),
- Thanks to the flexibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in various configurations, which increases their usage potential,
- Important function in modern technologies – they find application in computer drives, rotating machines, medical equipment and other advanced devices,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of NdFeB magnets:
- They can break when subjected to a sudden impact. If the magnets are exposed to physical collisions, 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 strengthens its overall strength,
- Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a humid environment. For outdoor use, we recommend using encapsulated magnets, such as those made of plastic,
- Limited ability to create threads in the magnet – the use of a housing is recommended,
- Health risk linked to microscopic shards may arise, in case of ingestion, which is important in the family environments. Furthermore, minuscule fragments from these products may disrupt scanning once in the system,
- Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications
Magnetic strength at its maximum – what contributes to it?
The given pulling force of the magnet represents the maximum force, assessed in ideal conditions, namely:
- with mild steel, used as a magnetic flux conductor
- having a thickness of no less than 10 millimeters
- with a refined outer layer
- with no separation
- in a perpendicular direction of force
- at room temperature
Lifting capacity in real conditions – factors
Practical lifting force is determined by elements, by priority:
- 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.
* Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance {between} the magnet and the plate decreases the holding force.
Handle with Care: Neodymium Magnets
Magnets made of neodymium are particularly delicate, which leads to damage.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
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. 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
The magnet coating is made of nickel, so be cautious 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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Neodymium magnets are the strongest magnets ever invented. Their power can surprise you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
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. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets will crack or alternatively crumble with careless connecting to each other. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.
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.
Be careful!
