Strengths and weaknesses of rare earth magnets.
Benefits
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets effectively resist against demagnetization caused by external fields,
- Thanks to the metallic finish, the coating of nickel, gold, or silver gives an clean appearance,
- Neodymium magnets generate maximum magnetic induction on a small surface, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the potential of flexible molding and customization to individualized needs, NdFeB magnets can be produced in a wide range of shapes and sizes, which amplifies use scope,
- Wide application in high-tech industry – they are utilized in mass storage devices, electromotive mechanisms, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We recommend a housing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- using a sheet made of mild steel, acting as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- under axial force direction (90-degree angle)
- in stable room temperature
Magnet lifting force in use – key factors
- Air gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Direction of force – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Magnet fragility
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them cracking into shards.
Data carriers
Do not bring magnets near a wallet, computer, or TV. The magnetism can destroy these devices and erase data from cards.
This is not a toy
Strictly keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact or opt for encased magnets.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Thermal limits
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Impact on smartphones
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Finger safety
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Dust is flammable
Powder generated during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
