Advantages as well as disadvantages of neodymium magnets.
Benefits
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- They feature excellent resistance to weakening of magnetic properties due to external fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the ability to customize to individual projects,
- Fundamental importance in electronics industry – they are used in data components, brushless drives, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- under conditions of no distance (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Warnings
Nickel coating and allergies
Some people have a hypersensitivity to Ni, which is the common plating for neodymium magnets. Frequent touching can result in dermatitis. It is best to use safety gloves.
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Conscious usage
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Heat warning
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Keep away from children
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Safe distance
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Pacemakers
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Bone fractures
Large magnets can break fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Combustion hazard
Powder generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Precision electronics
Note: rare earth magnets produce a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and navigation systems.
