Strengths as well as weaknesses of rare earth magnets.
Benefits
- They do not lose strength, even after approximately 10 years – the drop in power is only ~1% (based on measurements),
- They possess excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- Thanks to the elegant finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an clean appearance,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the option of precise forming and customization to specialized solutions, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which amplifies use scope,
- Wide application in high-tech industry – they are used in mass storage devices, electric drive systems, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- with zero gap (without impurities)
- during detachment in a direction vertical to the plane
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
GPS and phone interference
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, tablet, and GPS.
Do not underestimate power
Use magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their power.
Permanent damage
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.
Health Danger
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Beware of splinters
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Machining danger
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease working with magnets and use protective gear.
Crushing force
Large magnets can break fingers instantly. Do not place your hand betwixt two strong magnets.
Magnetic media
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
No play value
Strictly store magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.
