Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets possess huge magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the capacity to adapt to specific needs,
- Universal use in modern technologies – they are utilized in hard drives, motor assemblies, medical devices, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in small systems
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at room temperature
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (paint, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – too thin sheet does not close the flux, causing part of the flux to be lost to the other side.
- Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Pinching danger
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Protective goggles
NdFeB magnets are sintered ceramics, which means they are very brittle. Impact of two magnets will cause them shattering into small pieces.
Metal Allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid direct skin contact and opt for versions in plastic housing.
Adults only
Absolutely store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Impact on smartphones
GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Mechanical processing
Powder produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Implant safety
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Electronic hazard
Equipment safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Permanent damage
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
