Pros and cons of Nd2Fe14B magnets.
Advantages
- Their power remains stable, and after around 10 years it decreases only by ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working layer of the magnet turns out to be impressive,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in forming and the capacity to customize to client solutions,
- Versatile presence in innovative solutions – they serve a role in hard drives, drive modules, precision medical tools, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small elements of these products are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with an ground contact surface
- with total lack of distance (no impurities)
- during detachment in a direction vertical to the mounting surface
- at temperature room level
Magnet lifting force in use – key factors
- Clearance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was measured with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
Protect data
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Threat to navigation
A powerful magnetic field interferes with the operation of compasses in phones and GPS navigation. Maintain magnets near a smartphone to prevent breaking the sensors.
Operating temperature
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Skin irritation risks
A percentage of the population experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Extended handling might lead to an allergic reaction. It is best to wear safety gloves.
Handling rules
Exercise caution. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
ICD Warning
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to work with the magnets.
Product not for children
These products are not intended for children. Swallowing a few magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Bodily injuries
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Risk of cracking
Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets will cause them cracking into small pieces.
Machining danger
Machining of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
