Pros and cons of Nd2Fe14B magnets.
Pros
- They retain attractive force for almost 10 years – the loss is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by external disturbances,
- By covering with a lustrous coating of nickel, the element gains an professional look,
- Magnetic induction on the working layer of the magnet turns out to be maximum,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to modularity in shaping and the ability to modify to individual projects,
- Key role in electronics industry – they are utilized in hard drives, motor assemblies, medical equipment, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complicated shapes - recommended is casing - magnetic holder.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- on a base made of structural steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a plane perfectly flat
- with zero gap (no coatings)
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Keep away from children
Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
Handling rules
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Risk of cracking
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
GPS and phone interference
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Maximum temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Medical interference
Warning for patients: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Data carriers
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Pinching danger
Big blocks can crush fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
Nickel allergy
A percentage of the population suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact can result in skin redness. It is best to use safety gloves.
