Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- Their power remains stable, and after around 10 years it decreases only by ~1% (according to research),
- Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
- A magnet with a metallic nickel surface has an effective appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of custom creating and optimizing to defined requirements,
- Significant place in innovative solutions – they are commonly used in magnetic memories, electromotive mechanisms, diagnostic systems, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in compact constructions
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited possibility of producing nuts in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Highest magnetic holding force – what contributes to it?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose thickness is min. 10 mm
- with a surface free of scratches
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Impact on smartphones
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to prevent breaking the sensors.
Allergy Warning
Studies show that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, prevent direct skin contact or opt for coated magnets.
Eye protection
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Mechanical processing
Dust produced during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Heat warning
Avoid heat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Finger safety
Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Medical implants
Patients with a ICD must maintain an safe separation from magnets. The magnetic field can stop the functioning of the implant.
Swallowing risk
Adult use only. Tiny parts can be swallowed, causing serious injuries. Keep away from kids and pets.
Safe distance
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
