Pros and cons of neodymium magnets.
Advantages
- They do not lose magnetism, even over approximately ten years – the decrease in power is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny gold surface looks better,
- Magnetic induction on the working part of the magnet remains impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Possibility of accurate forming as well as adjusting to individual needs,
- Wide application in modern technologies – they serve a role in HDD drives, motor assemblies, advanced medical instruments, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Weaknesses
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these magnets can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with an polished contact surface
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Key elements affecting lifting force
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast 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
Sensitization to coating
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, avoid direct skin contact or select coated magnets.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them shattering into small pieces.
Health Danger
Warning for patients: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Compass and GPS
GPS units and mobile phones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Heat warning
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Finger safety
Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Product not for children
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Store away from kids and pets.
Safe operation
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Dust explosion hazard
Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Magnetic media
Avoid bringing magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
