Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under close interference source,
- In other words, due to the aesthetic finish of gold, the element is aesthetically pleasing,
- Magnetic induction on the surface of the magnet is maximum,
- 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...
- Thanks to versatility in designing and the capacity to customize to specific needs,
- Wide application in modern industrial fields – they serve a role in computer drives, brushless drives, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Highest magnetic holding force – what contributes to it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (surface-to-surface)
- under axial force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be escaped to the other side.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Handling rules
Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Nickel coating and allergies
Some people have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling can result in a rash. We recommend wear safety gloves.
Health Danger
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Permanent damage
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Safe distance
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Compass and GPS
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Adults only
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store out of reach of kids and pets.
Beware of splinters
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them breaking into shards.
Serious injuries
Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Fire warning
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
