Pros as well as cons of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the shiny surface of gold, the element looks attractive,
- Magnets are characterized by very high magnetic induction on the working surface,
- 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 potential of accurate shaping and adaptation to specialized requirements, magnetic components can be modeled in a variety of shapes and sizes, which expands the range of possible applications,
- Significant place in innovative solutions – they are utilized in HDD drives, electric drive systems, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in small systems
Cons
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- without any insulating layer between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
- Base smoothness – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Sensitization to coating
It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, avoid direct skin contact and select coated magnets.
Caution required
Use magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their power.
Beware of splinters
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them breaking into small pieces.
Data carriers
Do not bring magnets near a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.
Machining danger
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Do not overheat magnets
Keep cool. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Choking Hazard
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of children and animals.
GPS and phone interference
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Medical interference
Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Finger safety
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
