Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They do not lose power, even during around ten years – the decrease in power is only ~1% (based on measurements),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external field sources,
- Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
- Magnetic induction on the top side of the magnet turns out to be strong,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the ability of precise molding and adaptation to unique solutions, neodymium magnets can be manufactured in a variety of shapes and sizes, which increases their versatility,
- Wide application in future technologies – they are used in magnetic memories, electric motors, medical equipment, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we propose using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- with a cross-section no less than 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- during pulling in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to 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 significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – mild steel attracts best. Alloy steels reduce magnetic properties and lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
Swallowing risk
Neodymium magnets are not toys. Eating a few magnets can lead to them attracting across intestines, which constitutes a critical condition and requires urgent medical intervention.
Warning for heart patients
Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Pinching danger
Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Do not underestimate power
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Dust is flammable
Powder created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Beware of splinters
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Data carriers
Device Safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).
GPS and phone interference
Be aware: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.
Heat warning
Do not overheat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease working with magnets and wear gloves.
