Advantages as well as disadvantages of rare earth magnets.
Benefits
- Their strength is durable, and after around 10 years it decreases only by ~1% (theoretically),
- They have excellent resistance to magnetism drop as a result of opposing magnetic fields,
- By using a smooth coating of silver, the element presents an professional look,
- Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of free molding and customization to unique solutions, NdFeB magnets can be modeled in a variety of forms and dimensions, which makes them more universal,
- Key role in electronics industry – they find application in data components, brushless drives, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in small systems
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of low-carbon steel, functioning as a ideal flux conductor
- with a thickness of at least 10 mm
- with a surface free of scratches
- with total lack of distance (without impurities)
- under axial force vector (90-degree angle)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Distance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Do not drill into magnets
Powder produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Safe operation
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their power.
Compass and GPS
Remember: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your phone, device, and navigation systems.
Demagnetization risk
Avoid heat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Swallowing risk
Only for adults. Tiny parts can be swallowed, leading to severe trauma. Store out of reach of children and animals.
Warning for allergy sufferers
Some people suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause an allergic reaction. We strongly advise wear safety gloves.
Medical interference
Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Fragile material
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Bone fractures
Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
