Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets are distinguished by remarkably resistant to magnetic field loss caused by external magnetic fields,
- In other words, due to the shiny surface of nickel, the element gains a professional look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to the option of flexible molding and adaptation to specialized requirements, NdFeB magnets can be created in a variety of geometric configurations, which expands the range of possible applications,
- Fundamental importance in innovative solutions – they serve a role in computer drives, electromotive mechanisms, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these magnets are able to complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose thickness reaches at least 10 mm
- with an ideally smooth touching surface
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin steel does not close the flux, causing part of the flux to be lost to the other side.
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Warnings
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Shattering risk
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Permanent damage
Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Skin irritation risks
Some people suffer from a contact allergy to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause an allergic reaction. It is best to use safety gloves.
Keep away from electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.
Implant safety
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Product not for children
Only for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of kids and pets.
Safe distance
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Do not drill into magnets
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Serious injuries
Pinching hazard: The pulling power is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
