Advantages and disadvantages of neodymium magnets.
Pros
- They do not lose strength, even after approximately ten years – the decrease in power is only ~1% (based on measurements),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by magnetic disturbances,
- A magnet with a shiny nickel surface has an effective appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to freedom in forming and the capacity to adapt to client solutions,
- Key role in innovative solutions – they are used in HDD drives, motor assemblies, advanced medical instruments, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Limitations
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of making threads in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- using a base made of mild steel, functioning as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- without the slightest clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Fire risk
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Handling rules
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Fragile material
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Crushing risk
Watch your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
ICD Warning
People with a pacemaker have to keep an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
Keep away from electronics
An intense magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Keep magnets close to a smartphone to avoid breaking the sensors.
Heat warning
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Choking Hazard
These products are not toys. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a direct threat to life and necessitates immediate surgery.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and wear gloves.
Protect data
Do not bring magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
