Pros and cons of neodymium magnets.
Pros
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are exceptionally 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 be more visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- 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...
- Thanks to freedom in constructing and the ability to customize to unusual requirements,
- Key role in high-tech industry – they find application in HDD drives, electric drive systems, medical equipment, as well as industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard 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 devices can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- with a surface perfectly flat
- under conditions of no distance (metal-to-metal)
- under vertical force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Maximum temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Avoid contact if allergic
Studies show that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for versions in plastic housing.
Precision electronics
A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.
Electronic devices
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Health Danger
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Do not drill into magnets
Dust produced during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Crushing force
Big blocks can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Swallowing risk
Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.
Risk of cracking
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Powerful field
Handle with care. Neodymium magnets act from a long distance and connect with massive power, often faster than you can move away.
