Strengths as well as weaknesses of rare earth magnets.
Advantages
- They have stable power, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetism drop as a result of external magnetic sources,
- Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of precise machining and optimizing to specific requirements,
- Fundamental importance in modern industrial fields – they serve a role in magnetic memories, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complex shapes - recommended is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- with a cross-section of at least 10 mm
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Cards and drives
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Compass and GPS
Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Keep a separation from your mobile, device, and GPS.
Eye protection
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them cracking into shards.
Skin irritation risks
Studies show that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, avoid direct skin contact and select coated magnets.
Medical implants
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Conscious usage
Handle magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and do not underestimate their force.
Permanent damage
Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Product not for children
NdFeB magnets are not intended for children. Eating multiple magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
Finger safety
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
