Advantages and disadvantages of neodymium magnets.
Benefits
- Their strength is durable, and after approximately ten years it drops only by ~1% (theoretically),
- Neodymium magnets prove to be highly resistant to loss of magnetic properties caused by external interference,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working part of the magnet remains strong,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to freedom in designing and the capacity to modify to client solutions,
- Significant place in modern technologies – they are utilized in computer drives, brushless drives, medical equipment, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- 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 durability 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
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using cover - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices are able to complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ground contact surface
- without any air gap between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at temperature room level
Magnet lifting force in use – key factors
- Clearance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Product not for children
Strictly keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Caution required
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Power loss in heat
Control the heat. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
Fire warning
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Impact on smartphones
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Keep magnets near a device to prevent damaging the sensors.
Physical harm
Big blocks can smash fingers instantly. Never put your hand between two attracting surfaces.
ICD Warning
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
