Other products
Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They retain their magnetic properties even under external field action,
- By using a reflective layer of nickel, the element gains an proper look,
- Magnets exhibit very high magnetic induction on the surface,
- 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...
- Possibility of precise modeling as well as adjusting to defined applications,
- Universal use in modern technologies – they serve a role in data components, motor assemblies, precision medical tools, as well as other advanced devices.
- Thanks to their power density, 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 improves its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in creating threads and complex shapes in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic field
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Implant safety
Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Threat to navigation
GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Protect data
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact or select coated magnets.
Finger safety
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Caution required
Be careful. Neodymium magnets act from a distance and connect with massive power, often faster than you can move away.
Combustion hazard
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
No play value
These products are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires urgent medical intervention.
Beware of splinters
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them breaking into shards.
