Strengths as well as weaknesses of rare earth magnets.
Pros
- They retain magnetic properties for around ten years – the loss is just ~1% (according to analyses),
- Magnets effectively resist against loss of magnetization caused by ambient magnetic noise,
- By using a reflective coating of gold, the element gains an elegant look,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to freedom in shaping and the ability to adapt to client solutions,
- Huge importance in modern technologies – they are used in HDD drives, electric drive systems, diagnostic systems, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complicated shapes - recommended is cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an polished touching surface
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature room level
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be wasted into the air.
- Material type – ideal substrate is pure iron steel. Stainless steels may attract less.
- Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Operating temperature
Keep cool. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Shattering risk
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them shattering into shards.
Conscious usage
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their force.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and choose versions in plastic housing.
Medical implants
Patients with a ICD have to keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Magnetic interference
Note: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Pinching danger
Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Adults only
These products are not intended for children. Swallowing a few magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Fire warning
Powder generated during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
