Other products
Pros as well as cons of neodymium magnets.
Pros
- They do not lose strength, even after nearly 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
- They do not lose their magnetic properties even under strong external field,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the surface of the magnet remains maximum,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in designing and the capacity to customize to individual projects,
- Universal use in electronics industry – they are utilized in hard drives, brushless drives, medical devices, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks under impact, 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 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
- 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 secure oxidation and corrosion.
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a surface perfectly flat
- without any insulating layer between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Adults only
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets may result in them attracting across intestines, which constitutes a critical condition and requires urgent medical intervention.
Danger to pacemakers
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to handle the magnets.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop working with magnets and use protective gear.
Eye protection
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
Do not drill into magnets
Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Phone sensors
An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a device to avoid damaging the sensors.
Safe operation
Use magnets consciously. Their huge power can surprise even professionals. Be vigilant and respect their force.
Bodily injuries
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
