Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even during nearly ten years – the drop in strength is only ~1% (theoretically),
- They do not lose their magnetic properties even under external field action,
- By using a smooth layer of gold, the element gains an professional look,
- Magnetic induction on the surface of the magnet remains very high,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in constructing and the ability to adapt to individual projects,
- Significant place in electronics industry – they find application in hard drives, drive modules, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of mild steel, acting as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by even structure
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Key elements affecting lifting force
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Dust explosion hazard
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Precision electronics
GPS units and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Material brittleness
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Pacemakers
People with a pacemaker have to keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Finger safety
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Choking Hazard
Adult use only. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from children and animals.
Operating temperature
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
