Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for around 10 years – the loss is just ~1% (based on simulations),
- They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- In other words, due to the smooth finish of nickel, the element gains visual value,
- Magnets possess huge magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of accurate forming as well as modifying to complex requirements,
- Huge importance in future technologies – they are commonly used in hard drives, electric drive systems, medical devices, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Cons
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making threads in the magnet and complex shapes - preferred is casing - magnet mounting.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Highest magnetic holding force – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Magnetic interference
Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Thermal limits
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Eye protection
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Electronic devices
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Warning for heart patients
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Finger safety
Big blocks can crush fingers instantly. Do not put your hand between two attracting surfaces.
Dust is flammable
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Keep away from children
These products are not toys. Swallowing several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.
Handling rules
Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often faster than you can react.
Allergy Warning
Some people experience a sensitization to nickel, which is the common plating for NdFeB magnets. Extended handling might lead to skin redness. We strongly advise use safety gloves.
