Strengths as well as weaknesses of neodymium magnets.
Strengths
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- A magnet with a shiny nickel surface has better aesthetics,
- Magnets possess excellent magnetic induction on the surface,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Possibility of custom shaping as well as modifying to specific applications,
- Fundamental importance in innovative solutions – they find application in mass storage devices, electric drive systems, medical equipment, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the plane
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin plate does not accept the full field, causing part of the flux to be escaped to the other side.
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Cards and drives
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Thermal limits
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Physical harm
Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Immense force
Handle magnets with awareness. Their huge power can shock even professionals. Plan your moves and do not underestimate their force.
Eye protection
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Keep away from electronics
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Dust is flammable
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
This is not a toy
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of children and animals.
Health Danger
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose coated magnets.
