Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under close interference source,
- In other words, due to the metallic finish of gold, the element gains visual value,
- Magnetic induction on the surface of the magnet turns out to be maximum,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in forming and the capacity to modify to specific needs,
- Huge importance in electronics industry – they serve a role in mass storage devices, electric drive systems, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these products can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at temperature room level
What influences lifting capacity in practice
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the holding force.
Safety rules for work with neodymium magnets
Protect data
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Implant safety
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Danger to the youngest
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are very dangerous.
Threat to navigation
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Powerful field
Use magnets consciously. Their huge power can surprise even experienced users. Stay alert and respect their force.
Crushing risk
Big blocks can break fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Dust is flammable
Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Permanent damage
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Beware of splinters
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
