Pros and cons of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They feature excellent resistance to weakening of magnetic properties due to external magnetic sources,
- Thanks to the glossy finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an clean appearance,
- Magnets are distinguished by extremely high magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in designing and the ability to modify to client solutions,
- Versatile presence in advanced technology sectors – they are commonly used in mass storage devices, brushless drives, precision medical tools, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases 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.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in creating nuts and complicated forms in magnets, we propose using cover - magnetic holder.
- Possible danger 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 tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Highest magnetic holding force – what it depends on?
- using a plate made of mild steel, acting as a ideal flux conductor
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ground touching surface
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Key elements affecting lifting force
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
Precautions when working with neodymium magnets
Serious injuries
Mind your fingers. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
GPS and phone interference
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Heat sensitivity
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Allergic reactions
It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands and choose encased magnets.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Do not give to children
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.
Electronic hazard
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Handling guide
Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can move away.
Mechanical processing
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
