Pros as well as cons of rare earth magnets.
Strengths
- They do not lose power, even during approximately 10 years – the reduction in lifting capacity is only ~1% (according to tests),
- They show high resistance to demagnetization induced by external magnetic fields,
- A magnet with a smooth gold surface is more attractive,
- Magnetic induction on the surface of the magnet remains extremely intense,
- 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...
- In view of the possibility of free molding and adaptation to unique solutions, magnetic components can be modeled in a broad palette of geometric configurations, which makes them more universal,
- Huge importance in modern technologies – they serve a role in HDD drives, electromotive mechanisms, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex forms - preferred is casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a plate made of mild steel, acting as a circuit closing element
- with a cross-section no less than 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Air gap (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin steel does not close the flux, causing part of the power to be lost into the air.
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic properties and holding force.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Pacemakers
Warning for patients: Powerful magnets disrupt electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
Threat to navigation
Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Do not drill into magnets
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Crushing force
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Handling guide
Use magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their power.
Product not for children
Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from kids and pets.
Magnetic media
Do not bring magnets near a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Maximum temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Protective goggles
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Allergy Warning
Certain individuals suffer from a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching can result in an allergic reaction. We strongly advise wear safety gloves.
