Pros as well as cons of neodymium magnets.
Pros
- Their power is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets very well protect themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the reflective finish, the coating of nickel, gold, or silver-plated gives an professional appearance,
- Magnetic induction on the top side of the magnet remains strong,
- Neodymium magnets are characterized by very 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 freedom in constructing and the ability to customize to unusual requirements,
- Wide application in modern technologies – they are utilized in data components, brushless drives, medical devices, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their strength 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
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a thickness no less than 10 mm
- characterized by even structure
- with direct contact (without paint)
- under vertical application of breakaway force (90-degree angle)
- at standard ambient temperature
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
GPS and phone interference
Navigation devices and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Heat warning
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
ICD Warning
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Fire risk
Dust generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Respect the power
Be careful. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Beware of splinters
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Electronic devices
Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Serious injuries
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Avoid contact if allergic
Certain individuals have a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact can result in skin redness. We suggest wear safety gloves.
Do not give to children
Neodymium magnets are not toys. Accidental ingestion of several magnets can lead to them attracting across intestines, which poses a critical condition and necessitates immediate surgery.
