Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They retain full power for nearly 10 years – the loss is just ~1% (in theory),
- They are extremely resistant to demagnetization induced by external disturbances,
- By covering with a decorative layer of nickel, the element gains an aesthetic look,
- Magnetic induction on the working layer of the magnet turns out to be very high,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in shaping and the capacity to customize to unusual requirements,
- Huge importance in advanced technology sectors – they find application in hard drives, brushless drives, diagnostic systems, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Cons
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section minimum 10 mm
- with a plane free of scratches
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Key elements affecting lifting force
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, 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 maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Implant safety
Patients with a pacemaker have to maintain an large gap from magnets. The magnetism can interfere with the operation of the implant.
Heat warning
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
Precision electronics
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Safe distance
Device Safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Handling rules
Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.
Bone fractures
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Dust explosion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Adults only
Absolutely keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Nickel allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease working with magnets and wear gloves.
