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% (according to literature),
- They feature excellent resistance to magnetism drop when exposed to external fields,
- By applying a shiny coating of gold, the element gains an modern look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in forming and the ability to modify to specific needs,
- Versatile presence in innovative solutions – they are commonly used in mass storage devices, electric drive systems, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting 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 strength 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 advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these products can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – heating the magnet results in weakening of force. 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 attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Heat warning
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Keep away from computers
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Keep away from electronics
Note: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Swallowing risk
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.
Powerful field
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
ICD Warning
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Physical harm
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Do not drill into magnets
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
