Pros as well as cons of rare earth magnets.
Pros
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are extremely resistant to loss of magnetic properties caused by external magnetic fields,
- Thanks to the shiny finish, the layer of nickel, gold-plated, or silver-plated gives an professional appearance,
- Magnetic induction on the working part of the magnet turns out to be extremely intense,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual modeling as well as adjusting to specific needs,
- Huge importance in innovative solutions – they are used in data components, electromotive mechanisms, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of mild steel, serving as a circuit closing element
- whose thickness equals approx. 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding 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 penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Immense force
Handle with care. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can move away.
Data carriers
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Implant safety
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Fragile material
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.
Warning for allergy sufferers
A percentage of the population experience a sensitization to nickel, which is the standard coating for neodymium magnets. Prolonged contact can result in dermatitis. It is best to wear safety gloves.
Keep away from children
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.
Precision electronics
An intense magnetic field disrupts the functioning of compasses in phones and GPS navigation. Keep magnets close to a device to avoid breaking the sensors.
Maximum temperature
Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Serious injuries
Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Machining danger
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
