Advantages and disadvantages of neodymium magnets.
Advantages
- They do not lose strength, even during approximately 10 years – the drop in strength is only ~1% (according to tests),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- By using a smooth coating of gold, the element acquires an professional look,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of detailed creating and adjusting to complex conditions,
- Fundamental importance in future technologies – they are utilized in HDD drives, motor assemblies, diagnostic systems, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability 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, when using outdoors
- Limited ability of producing nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of mild steel, acting as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- with total lack of distance (without impurities)
- during pulling in a direction vertical to the plane
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
- Plate thickness – too thin sheet does not accept the full field, causing part of the flux to be escaped to the other side.
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Demagnetization risk
Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Health Danger
People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Risk of cracking
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Crushing risk
Large magnets can smash fingers instantly. Never put your hand between two strong magnets.
Mechanical processing
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Skin irritation risks
It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and select coated magnets.
Keep away from children
Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from kids and pets.
Magnetic media
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Phone sensors
A strong magnetic field disrupts the operation of magnetometers in phones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Caution required
Handle with care. Rare earth magnets act from a distance and snap with massive power, often quicker than you can move away.
