Magnetic properties of material N52
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Strengths as well as weaknesses of neodymium magnets.
Besides their durability, neodymium magnets are valued for these benefits:
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external magnetic fields,
- By covering with a decorative layer of nickel, the element has an nice look,
- Magnets are distinguished by maximum magnetic induction on the working surface,
- 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...
- Possibility of precise forming as well as modifying to concrete conditions,
- Wide application in advanced technology sectors – they serve a role in magnetic memories, brushless drives, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions
Disadvantages of NdFeB magnets:
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making threads in the magnet and complicated forms - preferred is a housing - mounting mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these products can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Maximum magnetic pulling force – what contributes to it?
The load parameter shown refers to the peak performance, obtained under laboratory conditions, meaning:
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- whose thickness equals approx. 10 mm
- characterized by even structure
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
Real force impacted by specific conditions, such as (from priority):
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
* Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance {between} the magnet and the plate lowers the holding force.
H&S for magnets
Implant safety
Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Thermal limits
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Machining danger
Powder produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Crushing risk
Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.
GPS Danger
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.
Warning for allergy sufferers
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or select versions in plastic housing.
Do not give to children
Strictly keep magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.
Data carriers
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Protective goggles
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Powerful field
Handle with care. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can react.
