Advantages as well as disadvantages of rare earth magnets.
Advantages
- Their strength remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They show high resistance to demagnetization induced by external field influence,
- In other words, due to the aesthetic finish of nickel, the element gains visual value,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of exact modeling as well as adapting to concrete requirements,
- Universal use in advanced technology sectors – they serve a role in mass storage devices, brushless drives, medical equipment, as well as modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited ability of creating nuts in the magnet and complicated forms - recommended is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of low-carbon steel, serving as a circuit closing element
- with a thickness of at least 10 mm
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Adults only
Adult use only. Small elements pose a choking risk, causing severe trauma. Store away from children and animals.
Shattering risk
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Hand protection
Large magnets can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Demagnetization risk
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Keep away from electronics
Be aware: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
Handling guide
Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease working with magnets and wear gloves.
Health Danger
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Dust explosion hazard
Dust produced during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
