Pros as well as cons of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by external interference,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet remains extremely intense,
- 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...
- Considering the option of accurate molding and adaptation to custom needs, magnetic components can be produced in a broad palette of forms and dimensions, which increases their versatility,
- Significant place in electronics industry – they are used in hard drives, motor assemblies, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- during pulling in a direction perpendicular to the plane
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Product not for children
Absolutely store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are life-threatening.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
Fragile material
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Safe operation
Exercise caution. Rare earth magnets act from a distance and snap with massive power, often quicker than you can react.
Electronic hazard
Avoid bringing magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Medical implants
Individuals with a heart stimulator have to keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Mechanical processing
Powder produced during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Bone fractures
Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
GPS Danger
A strong magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.
