Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They maintain their magnetic properties even under external field action,
- By covering with a decorative coating of silver, the element has an elegant look,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise creating and adapting to concrete applications,
- Huge importance in high-tech industry – they are utilized in data components, brushless drives, medical equipment, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, 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 during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- on a base made of structural steel, effectively closing the magnetic flux
- whose thickness reaches at least 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Distance (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate reduces the load capacity.
H&S for magnets
Finger safety
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Impact on smartphones
Be aware: rare earth magnets produce a field that interferes with precision electronics. Keep a separation from your mobile, device, and navigation systems.
Fire risk
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Risk of cracking
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Thermal limits
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Safe distance
Data protection: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
ICD Warning
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Caution required
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
No play value
Absolutely keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are tragic.
