Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even over nearly 10 years – the decrease in power is only ~1% (according to tests),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of exact machining and adjusting to concrete conditions,
- Significant place in electronics industry – they are utilized in computer drives, electric motors, diagnostic systems, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- 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.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using casing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with direct contact (no coatings)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Warnings
Nickel coating and allergies
Certain individuals suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Extended handling might lead to an allergic reaction. We strongly advise wear safety gloves.
Respect the power
Handle with care. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.
Swallowing risk
Absolutely keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Do not overheat magnets
Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Machining danger
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Crushing force
Big blocks can crush fingers instantly. Never place your hand betwixt two attracting surfaces.
Threat to electronics
Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Warning for heart patients
People with a pacemaker must keep an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Precision electronics
Note: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
