Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even over approximately 10 years – the reduction in strength is only ~1% (according to tests),
- Neodymium magnets are characterized by highly resistant to demagnetization caused by external field sources,
- By covering with a lustrous layer of nickel, the element has an elegant look,
- Magnets possess excellent magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of precise creating as well as modifying to concrete applications,
- Wide application in modern industrial fields – they find application in data components, electric motors, medical devices, as well as multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of low-carbon steel, acting as a magnetic yoke
- with a thickness minimum 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
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 load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Cards and drives
Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Allergy Warning
Certain individuals experience a sensitization to nickel, which is the common plating for NdFeB magnets. Extended handling may cause an allergic reaction. We suggest use safety gloves.
Protective goggles
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets leads to them shattering into shards.
Crushing force
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
No play value
Product intended for adults. Small elements can be swallowed, leading to severe trauma. Keep out of reach of children and animals.
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Pacemakers
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Fire warning
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Precision electronics
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Immense force
Use magnets consciously. Their huge power can shock even professionals. Plan your moves and respect their power.
