Pros as well as cons of neodymium magnets.
Benefits
- Their magnetic field remains stable, and after around 10 years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under strong external field,
- By using a shiny layer of nickel, the element acquires an elegant look,
- Magnetic induction on the working part of the magnet turns out to be strong,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of custom machining as well as adjusting to precise applications,
- Versatile presence in modern technologies – they are utilized in computer drives, motor assemblies, precision medical tools, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions
Limitations
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these products can complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a plate made of mild steel, serving as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Product not for children
These products are not toys. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Do not drill into magnets
Dust generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Magnetic interference
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Operating temperature
Watch the temperature. Exposing the magnet to high heat will ruin its properties and pulling force.
Medical interference
Patients with a heart stimulator must maintain an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Crushing force
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Sensitization to coating
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact and select coated magnets.
Respect the power
Handle with care. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can move away.
Threat to electronics
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them breaking into shards.
