Pros and cons of neodymium magnets.
Pros
- They do not lose magnetism, even during approximately ten years – the drop in lifting capacity is only ~1% (theoretically),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the glossy finish of gold, the element is aesthetically pleasing,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- In view of the option of accurate molding and adaptation to custom requirements, NdFeB magnets can be modeled in a variety of geometric configurations, which increases their versatility,
- Versatile presence in innovative solutions – they are used in computer drives, electromotive mechanisms, medical equipment, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of mild steel, acting as a magnetic yoke
- possessing a massiveness of min. 10 mm to avoid saturation
- with an polished contact surface
- with total lack of distance (no coatings)
- during pulling in a direction vertical to the plane
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Distance (betwixt the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be lost to the other side.
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Immense force
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Danger to the youngest
Always keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are fatal.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into shards.
Impact on smartphones
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets close to a smartphone to prevent breaking the sensors.
Crushing risk
Large magnets can smash fingers in a fraction of a second. Never place your hand between two strong magnets.
Cards and drives
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Nickel allergy
It is widely known that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose versions in plastic housing.
Power loss in heat
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Implant safety
Individuals with a pacemaker have to maintain an large gap from magnets. The magnetic field can disrupt the operation of the life-saving device.
