Pros and cons of Nd2Fe14B magnets.
Pros
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They have excellent resistance to magnetism drop due to external fields,
- A magnet with a metallic nickel surface has better aesthetics,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of custom machining as well as adapting to defined conditions,
- Fundamental importance in electronics industry – they serve a role in data components, motor assemblies, medical equipment, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in miniature devices
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 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 resistant to moisture
- Due to limitations in creating nuts and complicated forms in magnets, we recommend using casing - magnetic mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a plate made of mild steel, functioning as a circuit closing element
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- without any air gap between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (rust, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Physical harm
Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Permanent damage
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Immense force
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.
Data carriers
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and opt for coated magnets.
Keep away from electronics
Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Risk of cracking
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Medical implants
People with a heart stimulator must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the implant.
No play value
These products are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Combustion hazard
Machining of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
