Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their power remains stable, and after approximately ten years it decreases only by ~1% (according to research),
- Magnets very well defend themselves against demagnetization caused by foreign field sources,
- By covering with a shiny layer of gold, the element presents an aesthetic look,
- They show high magnetic induction at the operating surface, making them more effective,
- 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 freedom in forming and the capacity to customize to individual projects,
- Fundamental importance in advanced technology sectors – they serve a role in HDD drives, electric motors, diagnostic systems, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in producing threads and complicated shapes in magnets, we propose using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be wasted into the air.
- Steel type – mild steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Crushing risk
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Protect data
Do not bring magnets near a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Compass and GPS
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
Mechanical processing
Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Swallowing risk
These products are not suitable for play. Eating multiple magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
Medical implants
Patients with a pacemaker should keep an large gap from magnets. The magnetic field can disrupt the operation of the life-saving device.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact or select encased magnets.
Safe operation
Use magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their force.
Do not overheat magnets
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Magnets are brittle
NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them breaking into small pieces.
