Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- Their magnetic field is durable, and after around ten years it drops only by ~1% (according to research),
- They show high resistance to demagnetization induced by external field influence,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the option of flexible forming and adaptation to custom projects, NdFeB magnets can be produced in a variety of geometric configurations, which expands the range of possible applications,
- Versatile presence in electronics industry – they are used in magnetic memories, electromotive mechanisms, advanced medical instruments, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in small systems
Limitations
- To avoid cracks under impact, we recommend using special steel housings. 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by smoothness
- with total lack of distance (no impurities)
- under perpendicular force vector (90-degree angle)
- at room temperature
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, 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 maximum value.
- Base massiveness – too thin plate causes magnetic saturation, causing part of the flux to be escaped into the air.
- Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Precision electronics
A strong magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a device to avoid breaking the sensors.
Material brittleness
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Threat to electronics
Intense magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Choking Hazard
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.
Allergy Warning
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid direct skin contact and select versions in plastic housing.
Crushing risk
Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Conscious usage
Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.
Life threat
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Heat sensitivity
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Dust is flammable
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
