Pros and cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They possess excellent resistance to magnetism drop as a result of opposing magnetic fields,
- By covering with a decorative layer of silver, the element presents an proper look,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the potential of flexible shaping and customization to individualized requirements, NdFeB magnets can be produced in a wide range of shapes and sizes, which amplifies use scope,
- Fundamental importance in electronics industry – they serve a role in magnetic memories, electric drive systems, medical devices, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating nuts in the magnet and complex forms - recommended is a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- on a plate made of structural steel, effectively closing the magnetic field
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an polished touching surface
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not accept the full field, causing part of the flux to be lost into the air.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Physical harm
Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Threat to electronics
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Implant safety
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Phone sensors
GPS units and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Flammability
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Handling rules
Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their power.
Adults only
Absolutely store magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are life-threatening.
Nickel allergy
Some people have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. It is best to use protective gloves.
Operating temperature
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Fragile material
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
