Strengths and weaknesses of neodymium magnets.
Benefits
- They do not lose power, even over approximately 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by external field sources,
- Thanks to the elegant finish, the layer of nickel, gold-plated, or silver-plated gives an professional appearance,
- Magnetic induction on the surface of the magnet turns out to be strong,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of custom modeling and adapting to defined needs,
- Wide application in future technologies – they serve a role in HDD drives, brushless drives, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in creating nuts and complex shapes in magnets, we propose using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a thickness of at least 10 mm
- with an ground contact surface
- with zero gap (without coatings)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Handling guide
Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
Eye protection
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.
Crushing force
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Avoid contact if allergic
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and select versions in plastic housing.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Data carriers
Device Safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Dust explosion hazard
Dust generated during grinding of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Danger to pacemakers
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
GPS and phone interference
An intense magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid damaging the sensors.
