Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They retain attractive force for around 10 years – the loss is just ~1% (according to analyses),
- Magnets very well resist against loss of magnetization caused by foreign field sources,
- By using a shiny coating of nickel, the element presents an proper look,
- They feature high magnetic induction at the operating surface, which increases their power,
- 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...
- Possibility of custom machining as well as modifying to precise needs,
- Versatile presence in modern industrial fields – they are used in HDD drives, drive modules, precision medical tools, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex forms 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 context of child safety. It is also worth noting that small components of these products can be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Highest magnetic holding force – what affects it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- whose thickness reaches at least 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
No play value
Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are fatal.
Bodily injuries
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Nickel coating and allergies
A percentage of the population have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact can result in a rash. It is best to use protective gloves.
Conscious usage
Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can move away.
Fragile material
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Maximum temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Safe distance
Intense magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Machining danger
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Medical interference
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
GPS and phone interference
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
