Pros and cons of neodymium magnets.
Benefits
- They retain full power for almost ten years – the loss is just ~1% (in theory),
- Neodymium magnets are distinguished by highly resistant to magnetic field loss caused by external interference,
- A magnet with a shiny nickel surface looks better,
- Magnets are distinguished by excellent magnetic induction on the working surface,
- 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...
- Due to the possibility of flexible forming and customization to individualized solutions, neodymium magnets can be produced in a variety of shapes and sizes, which amplifies use scope,
- Wide application in modern technologies – they serve a role in data components, electric motors, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend cover - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension is min. 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (metal-to-metal)
- under axial force direction (90-degree angle)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Air gap (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Warnings
Machining danger
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Maximum temperature
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Danger to pacemakers
People with a pacemaker should maintain an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
GPS Danger
Note: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Safe distance
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Conscious usage
Handle with care. Neodymium magnets act from a distance and snap with huge force, often faster than you can react.
Bodily injuries
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Warning for allergy sufferers
Certain individuals suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Prolonged contact can result in a rash. We suggest wear safety gloves.
Do not give to children
Adult use only. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.
