Magnetic properties of material
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Strengths as well as weaknesses of NdFeB magnets.
Besides their high retention, neodymium magnets are valued for these benefits:
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They retain their magnetic properties even under strong external field,
- Thanks to the shimmering finish, the coating of nickel, gold, or silver gives an modern appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the option of flexible forming and customization to custom solutions, NdFeB magnets can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Huge importance in modern technologies – they are used in HDD drives, motor assemblies, diagnostic systems, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages of neodymium magnets:
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Magnetic strength at its maximum – what affects it?
Holding force of 1592 kg is a theoretical maximum value executed under the following configuration:
- using a plate made of mild steel, functioning as a ideal flux conductor
- whose thickness reaches at least 10 mm
- with an ideally smooth contact surface
- under conditions of no distance (surface-to-surface)
- under vertical force direction (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
Real force is influenced by working environment parameters, such as (from most important):
- Gap (betwixt the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
* Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance {between} the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Danger to pacemakers
For implant holders: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Operating temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Bodily injuries
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Skin irritation risks
Some people experience a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in skin redness. We recommend use safety gloves.
Product not for children
Product intended for adults. Small elements can be swallowed, leading to severe trauma. Store out of reach of kids and pets.
Fire warning
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this may cause fire.
Eye protection
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Precision electronics
Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Protect data
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Safe operation
Handle magnets consciously. Their immense force can shock even professionals. Plan your moves and respect their force.
