Advantages and disadvantages of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under strong external field,
- By covering with a smooth layer of silver, the element gains an aesthetic look,
- Magnetic induction on the surface of the magnet remains exceptional,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Considering the option of flexible shaping and adaptation to custom needs, magnetic components can be created in a variety of forms and dimensions, which increases their versatility,
- Universal use in advanced technology sectors – they serve a role in hard drives, electromotive mechanisms, precision medical tools, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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 as well as 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited ability of making nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, optimally conducting the magnetic field
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- with zero gap (without coatings)
- during pulling in a direction perpendicular to the mounting surface
- in stable room temperature
What influences lifting capacity in practice
- Distance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Medical interference
For implant holders: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Bodily injuries
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Dust explosion hazard
Powder generated during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Electronic devices
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Fragile material
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Keep away from electronics
An intense magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
This is not a toy
These products are not suitable for play. Swallowing a few magnets may result in them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
Thermal limits
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop handling magnets and use protective gear.
Powerful field
Be careful. Neodymium magnets act from a distance and connect with massive power, often quicker than you can react.
