Pros and cons of rare earth magnets.
Pros
- Their power is durable, and after approximately ten years it drops only by ~1% (according to research),
- They retain their magnetic properties even under external field action,
- Thanks to the shiny finish, the layer of nickel, gold, or silver gives an modern appearance,
- They show high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the ability of accurate shaping and adaptation to custom needs, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which expands the range of possible applications,
- Versatile presence in electronics industry – they are used in mass storage devices, electric motors, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using casing - magnetic mechanism.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane free of scratches
- without any clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Do not overheat magnets
Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Protect data
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Eye protection
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Respect the power
Handle magnets with awareness. Their immense force can shock even professionals. Plan your moves and respect their force.
Keep away from electronics
GPS units and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Implant safety
For implant holders: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Finger safety
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Flammability
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Nickel coating and allergies
A percentage of the population have a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact may cause an allergic reaction. We suggest use protective gloves.
No play value
NdFeB magnets are not suitable for play. Swallowing several magnets can lead to them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
