Pros and cons of Nd2Fe14B magnets.
Advantages
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- By covering with a lustrous coating of silver, the element presents an modern look,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in designing and the capacity to customize to complex applications,
- Huge importance in advanced technology sectors – they are commonly used in data components, electric motors, medical devices, as well as complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- 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
Magnetic strength at its maximum – what affects it?
- using a sheet made of high-permeability steel, serving as a circuit closing element
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane cleaned and smooth
- under conditions of no distance (metal-to-metal)
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be escaped into the air.
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Allergy Warning
A percentage of the population have a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Extended handling may cause a rash. We strongly advise use protective gloves.
Swallowing risk
Neodymium magnets are not intended for children. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
Beware of splinters
Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them cracking into small pieces.
Life threat
Warning for patients: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Magnetic media
Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Dust is flammable
Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Handling rules
Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can move away.
Finger safety
Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Be careful!
Thermal limits
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Compass and GPS
GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
