Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose power, even during approximately ten years – the decrease in power is only ~1% (according to tests),
- They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- A magnet with a shiny nickel surface has better aesthetics,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures reaching 230°C and above...
- Thanks to the ability of accurate forming and customization to unique projects, NdFeB magnets can be produced in a broad palette of forms and dimensions, which makes them more universal,
- Fundamental importance in advanced technology sectors – they are used in computer drives, motor assemblies, diagnostic systems, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in compact constructions
Weaknesses
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complex shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Highest magnetic holding force – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- with an ground touching surface
- without any insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of any layer (rust, dirt, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin sheet does not accept the full field, causing part of the flux to be lost into the air.
- Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Magnets are brittle
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Pacemakers
For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Protect data
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and pulling force.
Immense force
Exercise caution. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can move away.
Compass and GPS
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.
Combustion hazard
Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Adults only
Always store magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are very dangerous.
Crushing risk
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
