Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They do not lose their magnetic properties even under strong external field,
- By applying a lustrous layer of gold, the element acquires an professional look,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- In view of the ability of accurate molding and adaptation to unique solutions, NdFeB magnets can be produced in a variety of forms and dimensions, which makes them more universal,
- Huge importance in high-tech industry – they find application in hard drives, brushless drives, medical equipment, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complex forms - preferred is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a base made of mild steel, optimally conducting the magnetic field
- whose thickness equals approx. 10 mm
- with a plane cleaned and smooth
- with zero gap (no impurities)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Dust is flammable
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Risk of cracking
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Keep away from electronics
An intense magnetic field interferes with the operation of compasses in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Implant safety
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and use protective gear.
Electronic devices
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Permanent damage
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Choking Hazard
Neodymium magnets are not toys. Swallowing multiple magnets may result in them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
Hand protection
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
