Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They do not lose power, even after around 10 years – the drop in strength is only ~1% (according to tests),
- They maintain their magnetic properties even under close interference source,
- Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an aesthetic appearance,
- Magnetic induction on the surface of the magnet turns out to be very high,
- 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 accurate molding and customization to unique projects, NdFeB magnets can be modeled in a wide range of geometric configurations, which expands the range of possible applications,
- Versatile presence in modern technologies – they find application in HDD drives, electromotive mechanisms, medical devices, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases 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 and 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. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness minimum 10 mm
- with a plane perfectly flat
- without the slightest clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Beware of splinters
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Impact on smartphones
A powerful magnetic field interferes with the operation of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent breaking the sensors.
Bodily injuries
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Allergic reactions
It is widely known that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact and select versions in plastic housing.
Respect the power
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Adults only
These products are not suitable for play. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.
Fire warning
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Medical interference
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Magnetic media
Equipment safety: Strong magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
