Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external field influence,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are distinguished by very high magnetic induction on the active area,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Due to the ability of free forming and adaptation to custom needs, NdFeB magnets can be produced in a wide range of shapes and sizes, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they are utilized in data components, drive modules, medical devices, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in producing nuts and complex forms in magnets, we recommend using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- using a plate made of mild steel, functioning as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- with a plane free of scratches
- with zero gap (no paint)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- 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 nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.
Safe handling of neodymium magnets
Finger safety
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Do not give to children
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.
Maximum temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Threat to electronics
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
GPS and phone interference
GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Life threat
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Dust explosion hazard
Powder produced during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Handling guide
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Material brittleness
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Allergy Warning
Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and select versions in plastic housing.
