Strengths and weaknesses of neodymium magnets.
Pros
- Their strength is maintained, and after around ten years it decreases only by ~1% (according to research),
- They retain their magnetic properties even under external field action,
- A magnet with a shiny silver surface has better aesthetics,
- Neodymium magnets deliver maximum magnetic induction on a small area, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in forming and the capacity to modify to specific needs,
- Wide application in modern industrial fields – they are commonly used in HDD drives, electromotive mechanisms, precision medical tools, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in miniature devices
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing nuts and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- with a thickness minimum 10 mm
- with an polished touching surface
- with total lack of distance (no paint)
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (rust, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin plate does not close the flux, causing part of the power to be escaped to the other side.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and wear gloves.
Medical implants
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Finger safety
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Keep away from electronics
An intense magnetic field interferes with the functioning of compasses in phones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.
Handling guide
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can react.
Data carriers
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Swallowing risk
Only for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of children and animals.
Eye protection
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Thermal limits
Do not overheat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Combustion hazard
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
