Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They possess excellent resistance to magnetic field loss due to external fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets exhibit impressive magnetic induction on the active area,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the capacity to modify to client solutions,
- Significant place in future technologies – they are used in mass storage devices, electric drive systems, medical devices, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a thickness minimum 10 mm
- characterized by lack of roughness
- with total lack of distance (without impurities)
- under vertical force direction (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Distance – existence of foreign body (rust, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the flux to be escaped into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the load capacity.
Warnings
Dust explosion hazard
Machining of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Phone sensors
Remember: rare earth magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, tablet, and GPS.
Health Danger
People with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.
Threat to electronics
Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Nickel allergy
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or opt for encased magnets.
Shattering risk
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Powerful field
Use magnets with awareness. Their powerful strength can surprise even professionals. Be vigilant and respect their force.
Physical harm
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Choking Hazard
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
