Pros as well as cons of Nd2Fe14B magnets.
Benefits
- Their strength remains stable, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
- A magnet with a metallic nickel surface has an effective appearance,
- Neodymium magnets generate maximum magnetic induction on a contact point, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of exact shaping as well as modifying to atypical applications,
- Versatile presence in innovative solutions – they serve a role in computer drives, brushless drives, precision medical tools, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing threads and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these products can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by even structure
- without any insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Warnings
Danger to pacemakers
Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Caution required
Handle magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.
Material brittleness
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Flammability
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Data carriers
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Pinching danger
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Do not overheat magnets
Keep cool. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Compass and GPS
Be aware: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and GPS.
Do not give to children
Absolutely keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.
Warning for allergy sufferers
Studies show that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for versions in plastic housing.
