Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They retain their magnetic properties even under strong external field,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets are characterized by excellent magnetic induction on the working surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual shaping and adjusting to precise applications,
- Significant place in modern technologies – they are utilized in data components, drive modules, precision medical tools, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complex forms - recommended is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
H&S for magnets
Finger safety
Big blocks can smash fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Metal Allergy
A percentage of the population have a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to dermatitis. We recommend wear safety gloves.
Electronic hazard
Data protection: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
No play value
These products are not intended for children. Eating multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Danger to pacemakers
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Magnet fragility
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them shattering into shards.
GPS and phone interference
Navigation devices and smartphones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Flammability
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Operating temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Handling guide
Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
