Pros and cons of Nd2Fe14B magnets.
Pros
- Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
- They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
- In other words, due to the smooth surface of silver, the element becomes visually attractive,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in constructing and the ability to modify to complex applications,
- Universal use in advanced technology sectors – they find application in magnetic memories, electromotive mechanisms, precision medical tools, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of creating nuts in the magnet and complicated forms - preferred is casing - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- without the slightest clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature room level
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
Do not give to children
Only for adults. Small elements can be swallowed, causing intestinal necrosis. Store away from children and animals.
Operating temperature
Do not overheat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Safe operation
Handle with care. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.
Do not drill into magnets
Dust generated during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Skin irritation risks
Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or choose versions in plastic housing.
Pacemakers
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Crushing force
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Data carriers
Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Keep away from electronics
Note: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your phone, device, and GPS.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.
