Pros as well as cons of neodymium magnets.
Pros
- They retain attractive force for around ten years – the loss is just ~1% (according to analyses),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external field sources,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working layer of the magnet turns out to be extremely intense,
- 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...
- Possibility of individual shaping as well as optimizing to concrete requirements,
- Wide application in advanced technology sectors – they serve a role in hard drives, electric drive systems, diagnostic systems, as well as modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at room temperature
Lifting capacity in real conditions – factors
- Distance (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Health Danger
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Machining danger
Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Respect the power
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Magnetic interference
An intense magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Magnets are brittle
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Metal Allergy
A percentage of the population experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching may cause an allergic reaction. It is best to use protective gloves.
Magnetic media
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Crushing risk
Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
Maximum temperature
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. Damage is permanent.
Keep away from children
Always keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.
