Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even after nearly ten years – the decrease in strength is only ~1% (according to tests),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a metallic gold surface is more attractive,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Thanks to modularity in constructing and the capacity to modify to specific needs,
- Fundamental importance in advanced technology sectors – they are utilized in magnetic memories, motor assemblies, medical devices, as well as industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest casing - magnetic holder, due to difficulties in creating threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- without the slightest clearance between the magnet and steel
- under axial force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Clearance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be wasted to the other side.
- Material composition – not every steel reacts the same. High carbon content weaken the attraction effect.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Phone sensors
Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and GPS.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.
Finger safety
Protect your hands. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Immense force
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Keep away from children
Adult use only. Small elements can be swallowed, leading to serious injuries. Store out of reach of kids and pets.
Data carriers
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Protective goggles
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Heat warning
Avoid heat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
ICD Warning
For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Combustion hazard
Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
