Advantages as well as disadvantages of neodymium magnets.
Pros
- They retain full power for almost 10 years – the drop is just ~1% (based on simulations),
- Magnets effectively protect themselves against demagnetization caused by external fields,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are characterized by huge magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to freedom in shaping and the ability to customize to complex applications,
- Huge importance in electronics industry – they are used in HDD drives, electromotive mechanisms, diagnostic systems, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures 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 cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these magnets can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- using a plate made of low-carbon steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- with an ground contact surface
- without any insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at temperature room level
Magnet lifting force in use – key factors
- Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the flux to be wasted into the air.
- Material type – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
ICD Warning
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Magnetic media
Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Respect the power
Handle magnets with awareness. Their immense force can shock even professionals. Stay alert and respect their force.
GPS and phone interference
An intense magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
Do not give to children
Neodymium magnets are not toys. Eating a few magnets can lead to them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
Operating temperature
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Sensitization to coating
A percentage of the population experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to a rash. We suggest use protective gloves.
Hand protection
Pinching hazard: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Fragile material
NdFeB magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them shattering into shards.
Do not drill into magnets
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
