Strengths and weaknesses of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets perfectly defend themselves against demagnetization caused by ambient magnetic noise,
- By covering with a lustrous coating of nickel, the element presents an nice look,
- Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of exact modeling as well as adjusting to concrete requirements,
- Fundamental importance in high-tech industry – they serve a role in mass storage devices, brushless drives, medical devices, as well as technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
- 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
Maximum holding power of the magnet – what it depends on?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- under vertical force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Plate material – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal conditions – 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).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Magnets are brittle
Neodymium magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them breaking into shards.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Health Danger
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.
Machining danger
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
No play value
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store away from kids and pets.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness happens, cease working with magnets and wear gloves.
Respect the power
Exercise caution. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can move away.
Data carriers
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
GPS and phone interference
Navigation devices and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
Pinching danger
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
