Pros and cons of Nd2Fe14B magnets.
Advantages
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a smooth silver surface has better aesthetics,
- Magnets have very high magnetic induction on the outer side,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise creating and adapting to precise needs,
- Versatile presence in modern technologies – they are commonly used in HDD drives, electromotive mechanisms, advanced medical instruments, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, 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 is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of mild steel, functioning as a circuit closing element
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note 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.
- Steel type – low-carbon steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
- Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Danger to pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Handling rules
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Magnetic media
Do not bring magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Precision electronics
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Physical harm
Big blocks can break fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Adults only
Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Flammability
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Nickel coating and allergies
Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for coated magnets.
Beware of splinters
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
