Strengths and weaknesses of neodymium magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- Magnets perfectly resist against loss of magnetization caused by external fields,
- By applying a reflective layer of nickel, the element acquires an aesthetic look,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- 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 versatility in forming and the capacity to adapt to individual projects,
- Versatile presence in electronics industry – they find application in magnetic memories, electric motors, medical devices, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- At very 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.
- 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 and 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 usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is relatively high,
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- with zero gap (without paint)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
Health Danger
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Dust explosion hazard
Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Warning for allergy sufferers
It is widely known that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from direct skin contact or select encased magnets.
Physical harm
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
Choking Hazard
Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Immense force
Use magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their power.
GPS and phone interference
Remember: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
Magnet fragility
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into shards.
Cards and drives
Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
