Advantages as well as disadvantages of neodymium magnets.
Pros
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- A magnet with a shiny nickel surface has better aesthetics,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in forming and the ability to modify to specific needs,
- Universal use in future technologies – they are commonly used in mass storage devices, drive modules, medical equipment, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex shapes in magnets, we propose using cover - magnetic mechanism.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets can complicate diagnosis 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 it depends on?
- on a block made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- with zero gap (no paint)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the load capacity.
Skin irritation risks
Certain individuals have a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling may cause an allergic reaction. We suggest wear protective gloves.
Life threat
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Keep away from computers
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Eye protection
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Compass and GPS
Note: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, device, and navigation systems.
Demagnetization risk
Do not overheat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
This is not a toy
Neodymium magnets are not toys. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Dust is flammable
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Handling guide
Use magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their force.
Crushing risk
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
