Pros as well as cons of neodymium magnets.
Strengths
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- They feature excellent resistance to magnetic field loss due to external fields,
- Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- 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 flexibility in shaping and the ability to customize to specific needs,
- Key role in modern technologies – they are used in mass storage devices, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage 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 improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest 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
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- with total lack of distance (without impurities)
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Air gap (betwixt the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the load capacity.
Warnings
Safe distance
Intense magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Hand protection
Big blocks can crush fingers instantly. Never put your hand betwixt two strong magnets.
Threat to navigation
GPS units and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Danger to pacemakers
Patients with a heart stimulator must keep an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop working with magnets and use protective gear.
Do not overheat magnets
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Danger to the youngest
Absolutely keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets clamping inside the body are tragic.
Fire warning
Powder created during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Respect the power
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Eye protection
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
