Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They are resistant to demagnetization induced by external magnetic fields,
- By covering with a reflective coating of nickel, the element gains an professional look,
- Magnetic induction on the top side of the magnet turns out to be maximum,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Thanks to flexibility in shaping and the capacity to modify to specific needs,
- Fundamental importance in advanced technology sectors – they are commonly used in computer drives, electromotive mechanisms, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these products can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- on a block made of structural steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Keep away from computers
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Combustion hazard
Dust created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Fragile material
Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Medical implants
Patients with a ICD should maintain an large gap from magnets. The magnetic field can interfere with the operation of the implant.
Threat to navigation
An intense magnetic field negatively affects the functioning of compasses in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Bone fractures
Large magnets can smash fingers instantly. Never put your hand between two strong magnets.
Nickel allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact and select versions in plastic housing.
Product not for children
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.
Heat sensitivity
Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
