Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They show high resistance to demagnetization induced by external disturbances,
- In other words, due to the metallic surface of gold, the element gains visual value,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of accurate modeling and modifying to defined requirements,
- Wide application in modern technologies – they are commonly used in magnetic memories, brushless drives, medical devices, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of creating threads in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with an polished contact surface
- without any air gap between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Demagnetization risk
Do not overheat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Data carriers
Do not bring magnets close to a wallet, laptop, or screen. The magnetic field can destroy these devices and wipe information from cards.
Respect the power
Use magnets with awareness. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.
Nickel coating and allergies
Certain individuals suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. We suggest use safety gloves.
Implant safety
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
No play value
Neodymium magnets are not suitable for play. Swallowing multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires urgent medical intervention.
Finger safety
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Flammability
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Beware of splinters
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Phone sensors
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
