Pros and cons of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even after nearly 10 years – the reduction in power is only ~1% (according to tests),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by magnetic disturbances,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Considering the possibility of free molding and adaptation to specialized needs, NdFeB magnets can be produced in a wide range of geometric configurations, which expands the range of possible applications,
- Key role in high-tech industry – they are utilized in mass storage devices, brushless drives, advanced medical instruments, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. 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 rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complex shapes - recommended is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- without any insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at ambient temperature room level
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the holding force.
H&S for magnets
Medical interference
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Eye protection
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Crushing force
Danger of trauma: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Safe operation
Use magnets with awareness. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their force.
Product not for children
Only for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of children and animals.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
Combustion hazard
Machining of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Magnetic interference
GPS units and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Safe distance
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Demagnetization risk
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and strength.
