Strengths and weaknesses of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by external field influence,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the ability to modify to client solutions,
- Universal use in future technologies – they find application in HDD drives, motor assemblies, precision medical tools, also modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize 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 extremely resistant to heat
- 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
- Limited ability of creating nuts in the magnet and complicated shapes - preferred is a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- on a base made of mild steel, effectively closing the magnetic flux
- whose thickness reaches at least 10 mm
- with a surface free of scratches
- without the slightest air gap between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at room temperature
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Dust explosion hazard
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Allergy Warning
A percentage of the population have a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to dermatitis. We recommend wear safety gloves.
Beware of splinters
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them shattering into shards.
Data carriers
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Crushing risk
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Maximum temperature
Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
No play value
Strictly keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
Respect the power
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Warning for heart patients
People with a heart stimulator should keep an large gap from magnets. The magnetism can stop the functioning of the implant.
Compass and GPS
Remember: neodymium magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
