Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- Their magnetic field is durable, and after around ten years it decreases only by ~1% (theoretically),
- Neodymium magnets are characterized by remarkably resistant to loss of magnetic properties caused by external interference,
- In other words, due to the metallic surface of silver, the element looks attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise machining as well as adjusting to specific needs,
- Significant place in modern industrial fields – they serve a role in data components, brushless drives, medical devices, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a sheet made of mild steel, serving as a magnetic yoke
- with a thickness no less than 10 mm
- with a plane free of scratches
- with direct contact (without paint)
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Plate material – mild steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Conscious usage
Be careful. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Sensitization to coating
A percentage of the population have a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching might lead to an allergic reaction. We suggest use safety gloves.
Beware of splinters
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Electronic hazard
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
GPS and phone interference
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Flammability
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Serious injuries
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Danger to pacemakers
Patients with a heart stimulator must keep an large gap from magnets. The magnetism can disrupt the operation of the life-saving device.
No play value
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
