Strengths and weaknesses of rare earth magnets.
Advantages
- They retain full power for almost ten years – the loss is just ~1% (according to analyses),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- They show high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the ability of flexible forming and customization to unique requirements, NdFeB magnets can be manufactured in a broad palette of geometric configurations, which increases their versatility,
- Huge importance in future technologies – they are utilized in computer drives, electric motors, diagnostic systems, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating threads in the magnet and complex shapes - recommended is casing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of min. 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 (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Clearance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Base massiveness – too thin sheet does not accept the full field, causing part of the power to be escaped to the other side.
- Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
GPS and phone interference
An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Threat to electronics
Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Warning for heart patients
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Fragile material
Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Dust explosion hazard
Dust produced during cutting of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Operating temperature
Do not overheat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Allergic reactions
It is widely known that nickel (the usual finish) is a common allergen. If your skin reacts to metals, prevent direct skin contact and select versions in plastic housing.
Choking Hazard
Always store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.
Bodily injuries
Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Do not underestimate power
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.
