Advantages and disadvantages of rare earth magnets.
Pros
- They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets are highly resistant to demagnetization caused by external field sources,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the top side of the magnet remains extremely intense,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in designing and the ability to adapt to specific needs,
- Universal use in electronics industry – they serve a role in hard drives, electromotive mechanisms, diagnostic systems, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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 while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- with total lack of distance (no paint)
- under axial application of breakaway force (90-degree angle)
- at temperature room level
Determinants of lifting force in real conditions
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Handling rules
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Fire warning
Dust created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
This is not a toy
NdFeB magnets are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.
Safe distance
Data protection: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Heat sensitivity
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Phone sensors
A powerful magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to prevent damaging the sensors.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease handling magnets and use protective gear.
Serious injuries
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
ICD Warning
Patients with a ICD should keep an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Material brittleness
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
