Pros and cons of Nd2Fe14B magnets.
Advantages
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- Magnets very well defend themselves against loss of magnetization caused by external fields,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets generate maximum magnetic induction on a their surface, which increases force concentration,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in shaping and the capacity to customize to client solutions,
- Significant place in advanced technology sectors – they serve a role in hard drives, drive modules, precision medical tools, and technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a base made of mild steel, optimally conducting the magnetic field
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Gap (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Allergy Warning
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid direct skin contact and choose versions in plastic housing.
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Safe distance
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Keep away from children
NdFeB magnets are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.
Threat to navigation
Be aware: rare earth magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and GPS.
Do not drill into magnets
Powder created during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Bone fractures
Large magnets can break fingers instantly. Under no circumstances place your hand between two strong magnets.
Magnet fragility
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Do not overheat magnets
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Pacemakers
Patients with a heart stimulator must keep an absolute distance from magnets. The magnetism can interfere with the functioning of the life-saving device.
