Pros as well as cons of neodymium magnets.
Advantages
- They retain full power for almost 10 years – the drop is just ~1% (based on simulations),
- Neodymium magnets are exceptionally resistant to loss of magnetic properties caused by magnetic disturbances,
- In other words, due to the glossy finish of gold, the element looks attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of accurate molding and adaptation to specialized solutions, magnetic components can be manufactured in a broad palette of shapes and sizes, which expands the range of possible applications,
- Universal use in high-tech industry – they are commonly used in computer drives, motor assemblies, medical devices, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their force 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic mechanism.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- characterized by even structure
- with zero gap (without coatings)
- during detachment in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be escaped into the air.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Do not underestimate power
Handle magnets consciously. Their immense force can shock even professionals. Be vigilant and respect their force.
Physical harm
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
No play value
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.
Heat sensitivity
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Dust is flammable
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Impact on smartphones
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.
ICD Warning
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact or select encased magnets.
Magnets are brittle
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Electronic hazard
Do not bring magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
