Advantages and disadvantages of neodymium magnets.
Benefits
- Their strength is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
- By using a smooth layer of gold, the element has an proper look,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- 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 the ability of flexible forming and adaptation to custom needs, magnetic components can be produced in a wide range of geometric configurations, which increases their versatility,
- Key role in modern industrial fields – they are utilized in HDD drives, electric drive systems, precision medical tools, and 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
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend cover - magnetic holder, due to difficulties in creating threads inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small components of these products can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum magnetic pulling force – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section minimum 10 mm
- with a plane perfectly flat
- with total lack of distance (without paint)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Clearance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 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.
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
H&S for magnets
Do not drill into magnets
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Operating temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Keep away from children
NdFeB magnets are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.
Threat to navigation
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Safe distance
Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Nickel allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
Danger to pacemakers
Warning for patients: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Crushing risk
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Handling guide
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.
