Pros as well as cons of Nd2Fe14B magnets.
Pros
- They retain attractive force for nearly 10 years – the loss is just ~1% (in theory),
- They are resistant to demagnetization induced by external field influence,
- A magnet with a metallic nickel surface has an effective appearance,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in designing and the capacity to customize to unusual requirements,
- Significant place in high-tech industry – they find application in magnetic memories, drive modules, 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 intense 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 decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing threads in the magnet and complex forms - recommended is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- without any air gap between the magnet and steel
- under vertical force vector (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the power to be wasted to the other side.
- Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
H&S for magnets
Cards and drives
Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Finger safety
Mind your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Combustion hazard
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Health Danger
Individuals with a ICD must keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Avoid contact if allergic
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact or select coated magnets.
Swallowing risk
Only for adults. Small elements can be swallowed, causing intestinal necrosis. Keep out of reach of kids and pets.
Safe operation
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Protective goggles
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
GPS Danger
A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Keep magnets near a smartphone to avoid damaging the sensors.
