Pros and cons of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
- They show high resistance to demagnetization induced by external field influence,
- A magnet with a smooth nickel surface looks better,
- Magnetic induction on the top side of the magnet turns out to be maximum,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of detailed machining and modifying to atypical requirements,
- Wide application in high-tech industry – they are utilized in hard drives, drive modules, diagnostic systems, and other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- 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
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin plate does not accept the full field, causing part of the flux to be wasted into the air.
- Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering 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, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Threat to electronics
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Beware of splinters
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them cracking into small pieces.
Heat sensitivity
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Dust explosion hazard
Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Product not for children
Always store magnets away from children. Choking hazard is high, and the consequences of magnets clamping inside the body are fatal.
Crushing risk
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
Powerful field
Be careful. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can move away.
Nickel coating and allergies
It is widely known that nickel (standard magnet coating) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or select versions in plastic housing.
Magnetic interference
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Pacemakers
Individuals with a heart stimulator have to maintain an safe separation from magnets. The magnetism can disrupt the operation of the implant.
