Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They do not lose power, even over around 10 years – the drop in strength is only ~1% (based on measurements),
- Neodymium magnets remain exceptionally resistant to demagnetization caused by magnetic disturbances,
- By applying a decorative layer of gold, the element presents an elegant look,
- Neodymium magnets achieve maximum magnetic induction on a small area, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in designing and the ability to modify to complex applications,
- Significant place in high-tech industry – they are utilized in hard drives, brushless drives, precision medical tools, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We recommend casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a surface perfectly flat
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Safe distance
Data protection: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Serious injuries
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Skin irritation risks
Some people experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause dermatitis. It is best to use protective gloves.
Conscious usage
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often faster than you can react.
No play value
Always store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Threat to navigation
A strong magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Warning for heart patients
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Heat sensitivity
Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Shattering risk
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Mechanical processing
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
