Advantages and disadvantages of neodymium magnets.
Advantages
- They retain full power for almost 10 years – the loss is just ~1% (according to analyses),
- Neodymium magnets remain highly resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the elegant finish, the plating of nickel, gold, or silver gives an modern appearance,
- Magnetic induction on the surface of the magnet is impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of exact forming and adapting to specific applications,
- Versatile presence in high-tech industry – they are used in hard drives, brushless drives, precision medical tools, as well as modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of creating nuts in the magnet and complex forms - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- using a plate made of high-permeability steel, serving as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- without any insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the metal), as even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Load vector – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
- Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safe handling of NdFeB magnets
Fragile material
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Medical implants
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Danger to the youngest
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Maximum temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Impact on smartphones
An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.
Combustion hazard
Dust generated during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Handling rules
Use magnets consciously. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their power.
Nickel allergy
Some people experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Extended handling might lead to dermatitis. We recommend wear safety gloves.
Magnetic media
Do not bring magnets close to a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Physical harm
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
