Strengths and weaknesses of neodymium magnets.
Pros
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They feature excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- Thanks to the smooth finish, the coating of nickel, gold, or silver-plated gives an clean appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Thanks to flexibility in designing and the capacity to modify to unusual requirements,
- Fundamental importance in modern technologies – they find application in data components, electromotive mechanisms, precision medical tools, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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 rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex forms in magnets, we propose using a housing - magnetic mount.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these magnets can 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 can limit application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of mild steel, acting as a ideal flux conductor
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Warnings
Protective goggles
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them breaking into shards.
Threat to navigation
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to avoid breaking the sensors.
Data carriers
Do not bring magnets near a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Fire risk
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Permanent damage
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Warning for heart patients
People with a ICD have to keep an large gap from magnets. The magnetism can disrupt the functioning of the life-saving device.
Immense force
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Crushing force
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Danger to the youngest
Absolutely keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.
Avoid contact if allergic
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or choose encased magnets.
