Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the smooth surface of nickel, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the potential of accurate shaping and customization to custom solutions, magnetic components can be produced in a wide range of forms and dimensions, which increases their versatility,
- Versatile presence in modern industrial fields – they are utilized in computer drives, drive modules, advanced medical instruments, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in creating threads and complicated forms in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets can disrupt the diagnostic process 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
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Metal type – different alloys attracts identically. High carbon content worsen the attraction effect.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
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. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
No play value
Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.
Health Danger
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.
Protective goggles
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them shattering into shards.
Immense force
Handle magnets consciously. Their huge power can shock even professionals. Plan your moves and respect their power.
Electronic hazard
Intense magnetic fields can destroy records on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from direct skin contact and select encased magnets.
Demagnetization risk
Control the heat. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
Bodily injuries
Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Phone sensors
An intense magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Keep magnets near a smartphone to avoid breaking the sensors.
Combustion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
