Pros as well as cons of neodymium magnets.
Benefits
- They retain attractive force for around ten years – the loss is just ~1% (based on simulations),
- They possess excellent resistance to weakening of magnetic properties when exposed to external fields,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnetic induction on the surface of the magnet remains strong,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the ability to customize to specific needs,
- Significant place in high-tech industry – they are commonly used in HDD drives, electromotive mechanisms, diagnostic systems, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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 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 usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Highest magnetic holding force – what contributes to it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Mechanical processing
Powder created during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Handling rules
Handle magnets consciously. Their immense force can shock even professionals. Plan your moves and do not underestimate their power.
Magnets are brittle
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Product not for children
Only for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of kids and pets.
Keep away from electronics
A powerful magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
Permanent damage
Avoid heat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Health Danger
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Skin irritation risks
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or opt for versions in plastic housing.
Electronic devices
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Serious injuries
Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
