Pros as well as cons of rare earth magnets.
Advantages
- They retain magnetic properties for around 10 years – the drop is just ~1% (based on simulations),
- They maintain their magnetic properties even under strong external field,
- In other words, due to the glossy finish of nickel, the element becomes visually attractive,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Considering the option of flexible molding and customization to specialized solutions, neodymium magnets can be created in a broad palette of geometric configurations, which increases their versatility,
- Wide application in future technologies – they are used in hard drives, electric drive systems, medical equipment, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complicated forms in magnets, we recommend using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a plate made of low-carbon steel, serving as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (surface-to-surface)
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Avoid contact if allergic
Certain individuals suffer from a contact allergy to nickel, which is the standard coating for NdFeB magnets. Frequent touching might lead to skin redness. It is best to use safety gloves.
Compass and GPS
Be aware: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.
Hand protection
Large magnets can smash fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Heat warning
Do not overheat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Dust explosion hazard
Dust created during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Do not give to children
Adult use only. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Threat to electronics
Do not bring magnets near a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Magnets are brittle
NdFeB magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them breaking into small pieces.
Handling guide
Use magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their force.
