Strengths as well as weaknesses of neodymium magnets.
Advantages
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They have excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- In other words, due to the glossy layer of nickel, the element gains a professional look,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the ability to customize to complex applications,
- Wide application in modern technologies – they find application in hard drives, drive modules, medical devices, also other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their power 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 durability 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
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a base made of mild steel, serving as a magnetic yoke
- whose transverse dimension reaches at least 10 mm
- with a surface perfectly flat
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- at temperature room level
What influences lifting capacity in practice
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
- Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate decreases the holding force.
Warnings
Handling rules
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Danger to pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Material brittleness
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Bone fractures
Big blocks can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.
Keep away from electronics
Note: rare earth magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and GPS.
Cards and drives
Do not bring magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Do not give to children
Only for adults. Small elements pose a choking risk, causing serious injuries. Keep out of reach of kids and pets.
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Operating temperature
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
