Advantages and disadvantages of rare earth magnets.
Pros
- They do not lose strength, even over around 10 years – the reduction in strength is only ~1% (according to tests),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a metallic gold surface is more attractive,
- Neodymium magnets ensure maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual creating and optimizing to individual applications,
- Key role in electronics industry – they serve a role in magnetic memories, electromotive mechanisms, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance 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.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- with the use of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section minimum 10 mm
- with a plane cleaned and smooth
- with total lack of distance (no coatings)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – too thin sheet does not close the flux, causing part of the flux to be lost into the air.
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Conscious usage
Use magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and do not underestimate their force.
Magnets are brittle
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Bodily injuries
Large magnets can break fingers instantly. Never put your hand between two attracting surfaces.
Medical implants
Individuals with a ICD must keep an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Nickel coating and allergies
Some people suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise wear protective gloves.
Fire risk
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Precision electronics
An intense magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to avoid damaging the sensors.
Danger to the youngest
Absolutely store magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.
Safe distance
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Power loss in heat
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
