Strengths as well as weaknesses of rare earth magnets.
Strengths
- They do not lose power, even after approximately 10 years – the drop in power is only ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- In other words, due to the reflective finish of nickel, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- In view of the option of flexible shaping and customization to unique needs, NdFeB magnets can be manufactured in a wide range of geometric configurations, which amplifies use scope,
- Huge importance in modern industrial fields – they are used in HDD drives, drive modules, precision medical tools, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- whose thickness reaches at least 10 mm
- with a surface perfectly flat
- without any insulating layer between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- at ambient temperature room level
Key elements affecting lifting force
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel does not close the flux, causing part of the flux to be wasted into the air.
- Material type – ideal substrate is pure iron steel. Cast iron may attract less.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Warnings
Do not underestimate power
Use magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their power.
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
This is not a toy
Always store magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Protect data
Do not bring magnets close to a purse, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Dust is flammable
Dust produced during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Implant safety
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Crushing force
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Fragile material
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Heat warning
Avoid heat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
