Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They retain full power for almost ten years – the drop is just ~1% (based on simulations),
- They possess excellent resistance to magnetic field loss when exposed to external fields,
- A magnet with a shiny gold surface has an effective appearance,
- Magnetic induction on the working layer of the magnet remains maximum,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Due to the ability of free forming and adaptation to custom projects, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Wide application in electronics industry – they are commonly used in computer drives, electromotive mechanisms, precision medical tools, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their strength 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a base made of structural steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- with total lack of distance (without coatings)
- during detachment in a direction vertical to the plane
- in stable room temperature
Lifting capacity in real conditions – factors
- Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Safe distance
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Physical harm
Large magnets can smash fingers instantly. Do not place your hand betwixt two strong magnets.
No play value
Adult use only. Small elements can be swallowed, leading to severe trauma. Store away from children and animals.
Medical interference
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Avoid contact if allergic
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact or select encased magnets.
Respect the power
Handle with care. Rare earth magnets act from a distance and connect with huge force, often quicker than you can move away.
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Precision electronics
Be aware: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and navigation systems.
