Pros as well as cons of neodymium magnets.
Strengths
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external field influence,
- Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of individual modeling and adapting to complex applications,
- Huge importance in innovative solutions – they are utilized in magnetic memories, electric motors, medical devices, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a plate made of mild steel, serving as a magnetic yoke
- whose thickness equals approx. 10 mm
- with an ground contact surface
- with total lack of distance (without coatings)
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
Key elements affecting lifting force
- Gap (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Physical harm
Danger of trauma: The pulling power is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Operating temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Keep away from computers
Powerful magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Phone sensors
An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.
Risk of cracking
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Danger to the youngest
Neodymium magnets are not suitable for play. Eating a few magnets can lead to them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Immense force
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
Skin irritation risks
A percentage of the population experience a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We strongly advise use safety gloves.
Medical implants
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
