Pros as well as cons of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even during nearly 10 years – the drop in strength is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external field influence,
- By using a decorative coating of nickel, the element has an modern look,
- Neodymium magnets ensure maximum magnetic induction on a small area, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Considering the option of free molding and customization to individualized projects, neodymium magnets can be modeled in a broad palette of forms and dimensions, which amplifies use scope,
- Huge importance in modern industrial fields – they are utilized in magnetic memories, drive modules, diagnostic systems, and multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of making threads in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- with zero gap (no impurities)
- under axial force vector (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped into the air.
- Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Health Danger
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Skin irritation risks
A percentage of the population have a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Extended handling might lead to dermatitis. It is best to wear safety gloves.
Safe distance
Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Immense force
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Thermal limits
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
GPS and phone interference
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Do not give to children
Always store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Fire risk
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Hand protection
Danger of trauma: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
