Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose power, even after nearly ten years – the drop in strength is only ~1% (based on measurements),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by external field sources,
- By applying a decorative coating of silver, the element gains an professional look,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in shaping and the capacity to modify to specific needs,
- Versatile presence in modern industrial fields – they find application in HDD drives, motor assemblies, medical equipment, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of producing threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these magnets are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a plate made of mild steel, functioning as a ideal flux conductor
- with a cross-section minimum 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be lost into the air.
- Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Do not underestimate power
Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Medical implants
Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Serious injuries
Large magnets can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
Flammability
Dust created during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Danger to the youngest
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Protective goggles
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
Data carriers
Do not bring magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Compass and GPS
A strong magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.
Power loss in heat
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Nickel coating and allergies
Certain individuals have a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact might lead to a rash. It is best to use safety gloves.
