Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain attractive force for nearly ten years – the loss is just ~1% (according to analyses),
- They retain their magnetic properties even under strong external field,
- A magnet with a metallic silver surface is more attractive,
- Magnetic induction on the surface of the magnet is maximum,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the ability of precise forming and adaptation to specialized requirements, NdFeB magnets can be produced in a variety of geometric configurations, which makes them more universal,
- Versatile presence in modern technologies – they serve a role in hard drives, electric drive systems, medical devices, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- They are prone to damage upon too strong 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 demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- possessing a thickness of at least 10 mm to avoid saturation
- with a surface free of scratches
- without the slightest air gap between the magnet and steel
- under axial force direction (90-degree angle)
- in stable room temperature
Practical lifting capacity: influencing factors
- Air gap (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Caution required
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Medical interference
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Shattering risk
Neodymium magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them shattering into shards.
Demagnetization risk
Control the heat. Heating the magnet to high heat will ruin its properties and pulling force.
Electronic hazard
Very strong magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
No play value
These products are not intended for children. Swallowing a few magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and requires urgent medical intervention.
Serious injuries
Danger of trauma: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
Magnetic interference
Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Allergy Warning
It is widely known that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from direct skin contact and opt for versions in plastic housing.
Flammability
Dust created during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
