Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain full power for nearly 10 years – the drop is just ~1% (based on simulations),
- Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external field sources,
- Thanks to the reflective finish, the coating of nickel, gold, or silver-plated gives an visually attractive appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Due to the potential of free molding and adaptation to custom requirements, magnetic components can be modeled in a variety of geometric configurations, which makes them more universal,
- Universal use in high-tech industry – they are used in mass storage devices, electric drive systems, medical devices, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets demagnetize 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Clearance – the presence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
Warnings
Electronic devices
Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose versions in plastic housing.
Implant safety
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Caution required
Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their power.
Heat sensitivity
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Dust explosion hazard
Powder produced during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Crushing risk
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Danger to the youngest
Neodymium magnets are not suitable for play. Eating several magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.
Impact on smartphones
Note: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
