Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under strong external field,
- Thanks to the shimmering finish, the plating of nickel, gold-plated, or silver-plated gives an clean appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the option of accurate molding and customization to specialized projects, NdFeB magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
- Wide application in innovative solutions – they find application in computer drives, motor assemblies, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest 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, when using outdoors
- We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Highest magnetic holding force – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with total lack of distance (without coatings)
- under perpendicular force direction (90-degree angle)
- at temperature room level
What influences lifting capacity in practice
- Clearance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Angle of force application – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface structure – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Powerful field
Be careful. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can react.
Electronic hazard
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Swallowing risk
Adult use only. Small elements can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Medical interference
Individuals with a heart stimulator have to keep an absolute distance from magnets. The magnetism can stop the operation of the implant.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease working with magnets and use protective gear.
Hand protection
Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
GPS and phone interference
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.
Flammability
Machining of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Power loss in heat
Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Magnets are brittle
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
