Advantages as well as disadvantages of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external interference,
- By covering with a reflective coating of nickel, the element gains an professional look,
- Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact modeling and modifying to atypical needs,
- Wide application in innovative solutions – they serve a role in HDD drives, motor assemblies, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a block made of structural steel, effectively closing the magnetic field
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Key elements affecting lifting force
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Magnetic interference
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Cards and drives
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Demagnetization risk
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Immense force
Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Protective goggles
Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them breaking into small pieces.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Bone fractures
Large magnets can break fingers instantly. Never put your hand between two strong magnets.
Medical interference
People with a ICD must maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Do not give to children
Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are fatal.
Dust explosion hazard
Fire warning: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
