Advantages as well as disadvantages of neodymium magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by magnetic disturbances,
- In other words, due to the metallic layer of nickel, the element looks attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the capacity to adapt to client solutions,
- Versatile presence in electronics industry – they find application in magnetic memories, brushless drives, precision medical tools, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems
Weaknesses
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their strength 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a plate made of mild steel, acting as a circuit closing element
- possessing a thickness of at least 10 mm to avoid saturation
- with a surface free of scratches
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Bodily injuries
Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Keep away from electronics
Note: rare earth magnets generate a field that confuses sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Nickel allergy
Some people experience a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Extended handling might lead to an allergic reaction. It is best to use safety gloves.
Health Danger
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Thermal limits
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Flammability
Machining of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Do not give to children
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store out of reach of kids and pets.
Eye protection
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Data carriers
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Safe operation
Handle with care. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can move away.
