Pros as well as cons of rare earth magnets.
Advantages
- Their strength remains stable, and after around 10 years it drops only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- By applying a decorative coating of gold, the element gains an proper look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in designing and the capacity to modify to client solutions,
- Versatile presence in future technologies – they find application in hard drives, electric motors, medical devices, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a sheet made of mild steel, acting as a circuit closing element
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
What influences lifting capacity in practice
- Gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Power loss in heat
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Threat to navigation
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Material brittleness
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them cracking into shards.
Physical harm
Risk of injury: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Threat to electronics
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Nickel coating and allergies
A percentage of the population have a contact allergy to Ni, which is the common plating for NdFeB magnets. Extended handling may cause dermatitis. We suggest wear safety gloves.
Swallowing risk
NdFeB magnets are not toys. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Respect the power
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Machining danger
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
