Strengths and weaknesses of neodymium magnets.
Benefits
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They do not lose their magnetic properties even under close interference source,
- By using a shiny layer of gold, the element gains an aesthetic look,
- Magnetic induction on the top side of the magnet is impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in shaping and the ability to modify to specific needs,
- Universal use in electronics industry – they are utilized in magnetic memories, motor assemblies, diagnostic systems, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in compact constructions
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using a housing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- using a plate made of low-carbon steel, functioning as a magnetic yoke
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a plane perfectly flat
- under conditions of no distance (surface-to-surface)
- under perpendicular force vector (90-degree angle)
- at conditions approx. 20°C
Key elements affecting lifting force
- Air gap (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Serious injuries
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Combustion hazard
Powder created during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Do not overheat magnets
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Choking Hazard
NdFeB magnets are not intended for children. Accidental ingestion of several magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.
Medical interference
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Risk of cracking
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
GPS and phone interference
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Electronic hazard
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Sensitization to coating
Some people have a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling can result in skin redness. We recommend use safety gloves.
