Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They show high resistance to demagnetization induced by external magnetic fields,
- A magnet with a shiny gold surface has better aesthetics,
- Magnets exhibit extremely high magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the ability of flexible molding and customization to specialized projects, NdFeB magnets can be created in a wide range of shapes and sizes, which increases their versatility,
- Versatile presence in high-tech industry – they are utilized in computer drives, electric motors, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems
Weaknesses
- Brittleness 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 recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- We suggest a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what contributes to it?
- using a plate made of low-carbon steel, serving as a ideal flux conductor
- whose transverse dimension reaches at least 10 mm
- with an ideally smooth contact surface
- without any air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature room level
Determinants of practical lifting force of a magnet
- Air gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Combustion hazard
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Skin irritation risks
Certain individuals have a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to skin redness. We suggest use protective gloves.
Medical interference
Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Precision electronics
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Physical harm
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Handling rules
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.
Keep away from computers
Device Safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Power loss in heat
Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Beware of splinters
Neodymium magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
No play value
Always store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are tragic.
