Advantages as well as disadvantages of rare earth magnets.
Strengths
- Their power remains stable, and after approximately ten years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under external field action,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are distinguished by impressive magnetic induction on the active area,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Due to the option of flexible molding and adaptation to unique requirements, neodymium magnets can be created in a variety of geometric configurations, which expands the range of possible applications,
- Huge importance in advanced technology sectors – they are commonly used in computer drives, electric drive systems, medical equipment, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its 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 corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these devices can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- using a base made of low-carbon steel, serving as a circuit closing element
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane perfectly flat
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Precautions when working with neodymium magnets
Electronic hazard
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Choking Hazard
Strictly keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
Flammability
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Sensitization to coating
Certain individuals experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact might lead to skin redness. We recommend use safety gloves.
Immense force
Exercise caution. Rare earth magnets attract from a long distance and snap with massive power, often quicker than you can move away.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them cracking into shards.
Pinching danger
Big blocks can break fingers instantly. Never put your hand between two strong magnets.
Magnetic interference
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Medical implants
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Heat warning
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
