Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even after nearly ten years – the reduction in lifting capacity is only ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties due to external fields,
- A magnet with a smooth silver surface is more attractive,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in constructing and the ability to customize to individual projects,
- Universal use in modern industrial fields – they find application in mass storage devices, brushless drives, precision medical tools, as well as industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing nuts and complicated forms in magnets, we propose using cover - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
H&S for magnets
ICD Warning
Patients with a heart stimulator have to keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Combustion hazard
Mechanical processing of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Protect data
Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Magnetic interference
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.
Magnet fragility
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Sensitization to coating
Studies show that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent direct skin contact or choose coated magnets.
Operating temperature
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
This is not a toy
Absolutely keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.
Crushing risk
Big blocks can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.
Safe operation
Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.
