Pros and cons of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even during approximately 10 years – the reduction in power is only ~1% (based on measurements),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the glossy finish of nickel, the element looks attractive,
- Magnets have very high magnetic induction on the surface,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of accurate creating as well as adjusting to specific applications,
- Huge importance in electronics industry – they are used in hard drives, electromotive mechanisms, advanced medical instruments, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex forms in magnets, we propose using casing - 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. Furthermore, small components of these products can disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Operating temperature
Watch the temperature. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Do not underestimate power
Handle magnets consciously. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Electronic hazard
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Crushing risk
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Allergic reactions
Studies show that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and choose coated magnets.
Impact on smartphones
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.
Material brittleness
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Implant safety
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Swallowing risk
Always store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are tragic.
