Advantages and disadvantages of neodymium magnets.
Benefits
- Their magnetic field remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- They maintain their magnetic properties even under strong external field,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are characterized by huge magnetic induction on the outer layer,
- 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...
- Possibility of detailed modeling as well as modifying to defined requirements,
- Versatile presence in innovative solutions – they are commonly used in hard drives, drive modules, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their force 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
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of mild steel, effectively closing the magnetic field
- with a thickness of at least 10 mm
- with an ground contact surface
- without any air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
H&S for magnets
Keep away from electronics
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Material brittleness
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them shattering into shards.
Heat sensitivity
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Bodily injuries
Large magnets can break fingers instantly. Under no circumstances put your hand between two strong magnets.
Health Danger
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
This is not a toy
Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
Flammability
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands or opt for encased magnets.
Electronic devices
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Do not underestimate power
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.
