Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- Their strength is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They are resistant to demagnetization induced by external field influence,
- In other words, due to the metallic layer of nickel, the element looks attractive,
- Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Due to the potential of precise forming and customization to custom requirements, magnetic components can be produced in a wide range of shapes and sizes, which makes them more universal,
- Fundamental importance in innovative solutions – they serve a role in magnetic memories, motor assemblies, medical devices, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions
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.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as 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 suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- 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
Detachment force of the magnet in optimal conditions – what it depends on?
- using a plate made of mild steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in stable room temperature
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be wasted into the air.
- Material type – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Keep away from electronics
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Warning for heart patients
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them shattering into shards.
Magnetic media
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
No play value
Always keep magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.
Combustion hazard
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Nickel coating and allergies
Some people suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to a rash. We suggest wear protective gloves.
Handling rules
Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.
Maximum temperature
Do not overheat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Hand protection
Large magnets can break fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
