Other proposals
Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external magnetic fields,
- A magnet with a shiny gold surface looks better,
- Magnetic induction on the working part of the magnet is impressive,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise modeling and modifying to complex applications,
- Fundamental importance in modern industrial fields – they are used in HDD drives, drive modules, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in compact constructions
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in creating nuts and complex forms in magnets, we recommend using cover - magnetic mount.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these magnets can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- with a thickness no less than 10 mm
- with a surface free of scratches
- without any insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Keep away from computers
Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Dust is flammable
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Risk of cracking
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them shattering into shards.
Thermal limits
Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and strength.
Impact on smartphones
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Crushing risk
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Life threat
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.
Product not for children
Neodymium magnets are not toys. Eating a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.
