Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even during around 10 years – the drop in lifting capacity is only ~1% (according to tests),
- Magnets perfectly defend themselves against demagnetization caused by foreign field sources,
- In other words, due to the reflective finish of gold, the element becomes visually attractive,
- Neodymium magnets deliver maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Considering the ability of flexible molding and customization to unique projects, neodymium magnets can be manufactured in a wide range of geometric configurations, which expands the range of possible applications,
- Wide application in future technologies – they find application in hard drives, brushless drives, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 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 and corrosion.
- We suggest a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane cleaned and smooth
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of any layer (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically 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 composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Phone sensors
Note: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.
Mechanical processing
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
This is not a toy
These products are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Health Danger
People with a pacemaker have to maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Magnetic media
Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Hand protection
Protect your hands. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Nickel allergy
Certain individuals suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Prolonged contact can result in a rash. We suggest wear protective gloves.
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Powerful field
Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their force.
Do not overheat magnets
Avoid heat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
