Magnetic properties of material N52
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Strengths and weaknesses of neodymium magnets.
In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
- Their strength is durable, and after around 10 years it decreases only by ~1% (according to research),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external magnetic fields,
- By covering with a lustrous layer of gold, the element has an proper look,
- They show high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Considering the option of free shaping and customization to custom projects, magnetic components can be produced in a wide range of forms and dimensions, which expands the range of possible applications,
- Universal use in electronics industry – they serve a role in computer drives, motor assemblies, diagnostic systems, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Problematic aspects of neodymium magnets and proposals for their use:
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing nuts in the magnet and complex forms - preferred is casing - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Maximum holding power of the magnet – what it depends on?
Breakaway force is the result of a measurement for ideal contact conditions, including:
- on a block made of structural steel, perfectly concentrating the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- under vertical force vector (90-degree angle)
- at room temperature
Determinants of lifting force in real conditions
Effective lifting capacity is influenced by specific conditions, mainly (from most important):
- Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
* Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance {between} the magnet’s surface and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Pacemakers
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Dust is flammable
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Data carriers
Data protection: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Phone sensors
A strong magnetic field interferes with the operation of compasses in phones and navigation systems. Keep magnets close to a smartphone to prevent breaking the sensors.
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Keep away from children
Always keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are tragic.
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and wear gloves.
Respect the power
Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their power.
