Advantages as well as disadvantages of neodymium magnets.
Pros
- They do not lose power, even after approximately 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- Neodymium magnets are extremely resistant to demagnetization caused by external field sources,
- In other words, due to the shiny surface of gold, the element gains a professional look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Possibility of detailed shaping and modifying to concrete needs,
- Fundamental importance in modern technologies – they are used in hard drives, electromotive mechanisms, diagnostic systems, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions
Limitations
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. 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 advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these devices are able to complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- whose transverse dimension is min. 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be lost into the air.
- Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Maximum temperature
Control the heat. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Medical implants
Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and use protective gear.
Shattering risk
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Finger safety
Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Precision electronics
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Respect the power
Handle magnets with awareness. Their immense force can shock even professionals. Be vigilant and do not underestimate their power.
Swallowing risk
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
Protect data
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Dust is flammable
Powder created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
