Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They retain attractive force for nearly 10 years – the drop is just ~1% (in theory),
- They have excellent resistance to magnetic field loss due to opposing magnetic fields,
- By applying a shiny coating of silver, the element acquires an aesthetic look,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of custom modeling and optimizing to defined requirements,
- Huge importance in modern technologies – they find application in mass storage devices, electric motors, precision medical tools, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their 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 very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing nuts in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what affects it?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- under vertical force vector (90-degree angle)
- in stable room temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Physical harm
Large magnets can crush fingers instantly. Under no circumstances put your hand between two attracting surfaces.
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, look for HT versions (H, SH, UH).
Pacemakers
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Safe operation
Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their power.
Shattering risk
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Nickel allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact and select encased magnets.
Swallowing risk
Strictly store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
Dust explosion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Compass and GPS
Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Electronic devices
Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
