Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are distinguished by very high magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to modularity in constructing and the capacity to customize to individual projects,
- Key role in modern technologies – they serve a role in computer drives, electromotive mechanisms, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- 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.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in realizing nuts and complicated shapes in magnets, we propose using a housing - magnetic mount.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- with total lack of distance (no coatings)
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet does not accept the full field, causing part of the flux to be escaped into the air.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic permeability and holding force.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Thermal limits
Watch the temperature. Heating the magnet to high heat will ruin its magnetic structure and strength.
Safe operation
Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can react.
Magnets are brittle
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Crushing risk
Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation happens, cease handling magnets and use protective gear.
Data carriers
Equipment safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Magnetic interference
Be aware: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Adults only
Adult use only. Small elements can be swallowed, causing serious injuries. Store away from children and animals.
Health Danger
Individuals with a pacemaker have to keep an large gap from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Fire risk
Machining of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
