Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets prove to be extremely resistant to demagnetization caused by external field sources,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to freedom in designing and the ability to customize to specific needs,
- Wide application in modern technologies – they serve a role in HDD drives, electric drive systems, diagnostic systems, and other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures 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 and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complicated forms - recommended is cover - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what affects it?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- with direct contact (without impurities)
- under vertical force direction (90-degree angle)
- in stable room temperature
Determinants of lifting force in real conditions
- Distance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (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 (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate reduces the holding force.
H&S for magnets
This is not a toy
Only for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Fire risk
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Permanent damage
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
Magnet fragility
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Crushing force
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Sensitization to coating
It is widely known that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for encased magnets.
Immense force
Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can react.
Health Danger
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Data carriers
Do not bring magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Phone sensors
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
