Advantages and disadvantages of rare earth magnets.
Pros
- They retain full power for almost ten years – the drop is just ~1% (according to analyses),
- Magnets very well defend themselves against demagnetization caused by external fields,
- By covering with a shiny coating of nickel, the element has an proper look,
- Magnets are distinguished by huge magnetic induction on the working surface,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of custom forming as well as adapting to defined applications,
- Universal use in electronics industry – they serve a role in data components, electric drive systems, medical equipment, and industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We recommend a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what affects it?
- on a base made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane perfectly flat
- with total lack of distance (no coatings)
- during detachment in a direction vertical to the plane
- in stable room temperature
Key elements affecting lifting force
- Gap (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Dust explosion hazard
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Magnetic media
Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
No play value
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Handling guide
Handle magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.
Medical interference
Individuals with a ICD must maintain an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
GPS and phone interference
Be aware: rare earth magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.
Shattering risk
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Physical harm
Large magnets can break fingers instantly. Do not put your hand between two strong magnets.
Power loss in heat
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Nickel allergy
Certain individuals experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to an allergic reaction. We recommend use safety gloves.
