Advantages and disadvantages of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets are characterized by extremely resistant to demagnetization caused by external interference,
- A magnet with a shiny gold surface looks better,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the capacity to modify to client solutions,
- Universal use in modern technologies – they serve a role in hard drives, electromotive mechanisms, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a base made of mild steel, functioning as a circuit closing element
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of NdFeB magnets
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Magnets are brittle
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Electronic devices
Do not bring magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Hand protection
Danger of trauma: The pulling power is so great that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Implant safety
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Swallowing risk
Only for adults. Tiny parts can be swallowed, causing serious injuries. Store away from children and animals.
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Combustion hazard
Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Threat to navigation
An intense magnetic field disrupts the operation of compasses in phones and navigation systems. Maintain magnets near a smartphone to avoid damaging the sensors.
