Pros and cons of rare earth magnets.
Benefits
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by external field influence,
- In other words, due to the glossy layer of gold, the element looks attractive,
- Magnetic induction on the working layer of the magnet remains impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Thanks to modularity in shaping and the ability to modify to unusual requirements,
- Wide application in high-tech industry – they are used in mass storage devices, brushless drives, medical equipment, also multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At very strong impacts they can crack, 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, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex forms - preferred is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these products are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – 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.
- Steel thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be escaped into the air.
- Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Warnings
Magnetic interference
A powerful magnetic field interferes with the operation of compasses in phones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Magnet fragility
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets leads to them breaking into shards.
Immense force
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Pinching danger
Big blocks can break fingers in a fraction of a second. Do not place your hand between two strong magnets.
Adults only
Absolutely keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are fatal.
Protect data
Do not bring magnets close to a purse, computer, or screen. The magnetism can destroy these devices and erase data from cards.
ICD Warning
Individuals with a ICD have to maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the life-saving device.
Power loss in heat
Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Flammability
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
