Pros and cons of neodymium magnets.
Pros
- Their strength is maintained, and after around ten years it drops only by ~1% (according to research),
- They are resistant to demagnetization induced by external magnetic fields,
- A magnet with a shiny nickel surface is more attractive,
- Magnets are characterized by very high magnetic induction on the outer layer,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of accurate forming and modifying to specific applications,
- Wide application in electronics industry – they find application in magnetic memories, brushless drives, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these products can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- in temp. approx. 20°C
What influences lifting capacity in practice
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be lost to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Fire risk
Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Phone sensors
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from direct skin contact and choose versions in plastic housing.
Keep away from computers
Do not bring magnets near a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Pacemakers
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
No play value
Strictly keep magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Finger safety
Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Powerful field
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often quicker than you can move away.
Eye protection
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into shards.
