Advantages and disadvantages of neodymium magnets.
Strengths
- Their power is durable, and after approximately ten years it decreases only by ~1% (according to research),
- Neodymium magnets are remarkably resistant to demagnetization caused by external magnetic fields,
- A magnet with a shiny nickel surface has an effective appearance,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the potential of accurate shaping and customization to unique solutions, NdFeB magnets can be modeled in a variety of geometric configurations, which amplifies use scope,
- Wide application in modern technologies – they are utilized in computer drives, drive modules, precision medical tools, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- 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.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Distance (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Permanent damage
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Keep away from electronics
Remember: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
ICD Warning
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose encased magnets.
Respect the power
Be careful. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.
Data carriers
Powerful magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Material brittleness
NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets leads to them cracking into shards.
Swallowing risk
Always store magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Crushing force
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
