Pros and cons of neodymium magnets.
Advantages
- They retain full power for nearly 10 years – the loss is just ~1% (in theory),
- Neodymium magnets remain extremely resistant to demagnetization caused by external interference,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- They feature high magnetic induction at the operating surface, which increases their power,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Considering the potential of flexible shaping and adaptation to individualized needs, NdFeB magnets can be produced in a broad palette of shapes and sizes, which makes them more universal,
- Versatile presence in modern technologies – they serve a role in mass storage devices, drive modules, medical devices, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness equals approx. 10 mm
- with an ideally smooth contact surface
- without any clearance between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Plate material – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Flammability
Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Fragile material
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them cracking into shards.
Power loss in heat
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Threat to navigation
GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Product not for children
Always keep magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.
Respect the power
Use magnets with awareness. Their huge power can shock even professionals. Be vigilant and respect their force.
Safe distance
Data protection: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Avoid contact if allergic
Some people suffer from a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Prolonged contact can result in an allergic reaction. We recommend use safety gloves.
Hand protection
Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Health Danger
Individuals with a heart stimulator must keep an absolute distance from magnets. The magnetism can stop the operation of the implant.
