Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their power is maintained, and after approximately ten years it drops only by ~1% (theoretically),
- They feature excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- By applying a reflective coating of nickel, the element presents an elegant look,
- Magnetic induction on the top side of the magnet remains exceptional,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Due to the potential of accurate forming and customization to specialized requirements, neodymium magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
- Huge importance in advanced technology sectors – they are commonly used in HDD drives, electric drive systems, medical equipment, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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 rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- with the use of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension is min. 10 mm
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be lost to the other side.
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
Warnings
Bone fractures
Large magnets can smash fingers in a fraction of a second. Do not place your hand between two strong magnets.
Electronic devices
Intense magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Handling guide
Exercise caution. Rare earth magnets act from a long distance and snap with huge force, often quicker than you can move away.
Do not give to children
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store out of reach of kids and pets.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Impact on smartphones
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.
Do not drill into magnets
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Do not overheat magnets
Avoid heat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Allergic reactions
Some people suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause skin redness. It is best to use protective gloves.
Medical implants
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
