Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- Their power is durable, and after around 10 years it drops only by ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties when exposed to external fields,
- By applying a decorative layer of gold, the element acquires an elegant look,
- Magnets exhibit very high magnetic induction on the outer side,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of accurate machining as well as adjusting to atypical needs,
- Significant place in modern technologies – they are utilized in magnetic memories, motor assemblies, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Limitations
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing nuts in the magnet and complex forms - preferred is casing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of at least 10 mm to avoid saturation
- with a surface free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Clearance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost into the air.
- Plate material – mild steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
This is not a toy
Adult use only. Small elements pose a choking risk, leading to serious injuries. Store away from kids and pets.
Do not drill into magnets
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
Implant safety
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Cards and drives
Do not bring magnets close to a wallet, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Physical harm
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Be careful!
Conscious usage
Exercise caution. Rare earth magnets act from a distance and connect with huge force, often faster than you can react.
GPS and phone interference
A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.
Magnet fragility
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Nickel allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease handling magnets and wear gloves.
