Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by external magnetic fields,
- By applying a smooth coating of silver, the element acquires an elegant look,
- Magnets possess impressive magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of precise forming and adaptation to custom requirements, neodymium magnets can be modeled in a broad palette of forms and dimensions, which increases their versatility,
- Versatile presence in high-tech industry – they are used in magnetic memories, motor assemblies, precision medical tools, and technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- NdFeB 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Plate texture – ground elements guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
GPS and phone interference
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Mechanical processing
Powder produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop working with magnets and wear gloves.
Physical harm
Big blocks can break fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Warning for heart patients
Individuals with a heart stimulator must keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Risk of cracking
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and strength.
Danger to the youngest
Absolutely keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.
Handling rules
Handle with care. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can move away.
Protect data
Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
