Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even after around 10 years – the decrease in lifting capacity is only ~1% (according to tests),
- They have excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Thanks to modularity in shaping and the capacity to customize to complex applications,
- Versatile presence in high-tech industry – they serve a role in hard drives, drive modules, medical devices, as well as multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a plate made of mild steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the metal), because 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).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – hot environment reduces 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 the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
Warnings
Compass and GPS
A strong magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent breaking the sensors.
Flammability
Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Keep away from computers
Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Fragile material
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them breaking into shards.
Danger to pacemakers
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
No play value
These products are not toys. Swallowing multiple magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Handling guide
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Power loss in heat
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
