Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose power, even during approximately 10 years – the reduction in strength is only ~1% (according to tests),
- They do not lose their magnetic properties even under external field action,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the capacity to adapt to complex applications,
- Universal use in future technologies – they are used in data components, drive modules, diagnostic systems, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complex forms in magnets, we propose using casing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an polished contact surface
- without the slightest air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
What influences lifting capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Conscious usage
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Combustion hazard
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Hand protection
Watch your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Threat to navigation
Be aware: rare earth magnets produce a field that confuses precision electronics. Maintain a separation from your phone, tablet, and navigation systems.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Medical interference
People with a heart stimulator have to keep an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
Warning for allergy sufferers
A percentage of the population have a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. We suggest use safety gloves.
Protect data
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Demagnetization risk
Keep cool. Neodymium magnets are sensitive to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Swallowing risk
Neodymium magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which constitutes a severe health hazard and requires immediate surgery.
