Other offers
Advantages as well as disadvantages of neodymium magnets.
Benefits
- They do not lose power, even over around 10 years – the drop in lifting capacity is only ~1% (based on measurements),
- They are extremely resistant to demagnetization induced by external disturbances,
- A magnet with a smooth silver surface is more attractive,
- Magnets have exceptionally strong magnetic induction on the outer side,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the ability to customize to individual projects,
- Universal use in modern technologies – they are used in HDD drives, brushless drives, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of producing threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices can be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a base made of high-permeability steel, serving as a circuit closing element
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a plane perfectly flat
- without any clearance between the magnet and steel
- under vertical force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel causes magnetic saturation, causing part of the flux to be lost into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Mechanical processing
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Implant safety
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Risk of cracking
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Allergy Warning
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and wear gloves.
Heat sensitivity
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Physical harm
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Cards and drives
Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Handling guide
Handle with care. Neodymium magnets act from a distance and snap with huge force, often faster than you can react.
GPS Danger
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Choking Hazard
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from kids and pets.
