Strengths as well as weaknesses of neodymium magnets.
Pros
- Their magnetic field is durable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets remain remarkably resistant to magnetic field loss caused by magnetic disturbances,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working part of the magnet turns out to be very high,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- In view of the ability of accurate shaping and customization to specialized needs, magnetic components can be modeled in a broad palette of forms and dimensions, which makes them more universal,
- Versatile presence in innovative solutions – they are commonly used in data components, drive modules, precision medical tools, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- 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.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what it depends on?
- using a plate made of high-permeability steel, functioning as a ideal flux conductor
- with a thickness no less than 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the plane
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Plate thickness – too thin plate does not close the flux, causing part of the power to be escaped into the air.
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with neodymium magnets
Compass and GPS
A strong magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Physical harm
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Product not for children
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.
Operating temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Keep away from computers
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them breaking into shards.
Danger to pacemakers
People with a heart stimulator should keep an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Metal Allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop working with magnets and wear gloves.
Dust is flammable
Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
