Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They retain full power for almost ten years – the loss is just ~1% (based on simulations),
- They retain their magnetic properties even under close interference source,
- In other words, due to the glossy layer of gold, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- Possibility of precise modeling as well as adapting to concrete conditions,
- Fundamental importance in modern technologies – they are used in magnetic memories, brushless drives, advanced medical instruments, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength 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 stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small elements of these magnets can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of mild steel, functioning as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with an ground contact surface
- under conditions of gap-free contact (metal-to-metal)
- under vertical application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Physical harm
Big blocks can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Adults only
NdFeB magnets are not intended for children. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Keep away from electronics
A strong magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid breaking the sensors.
Implant safety
For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Warning for allergy sufferers
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact and select encased magnets.
Conscious usage
Be careful. Neodymium magnets attract from a distance and snap with massive power, often faster than you can react.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Magnetic media
Do not bring magnets near a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Do not drill into magnets
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
