Pros as well as cons of rare earth magnets.
Benefits
- They retain attractive force for around 10 years – the loss is just ~1% (in theory),
- They are resistant to demagnetization induced by external field influence,
- Thanks to the smooth finish, the coating of Ni-Cu-Ni, gold, or silver gives an professional appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the capacity to modify to client solutions,
- Huge importance in advanced technology sectors – they are used in magnetic memories, motor assemblies, medical devices, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in small systems
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their force 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
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating nuts in the magnet and complex shapes - recommended is a housing - magnet mounting.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- using a base made of mild steel, functioning as a magnetic yoke
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Steel type – mild steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Dust is flammable
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Respect the power
Be careful. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can move away.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop working with magnets and wear gloves.
Do not give to children
Neodymium magnets are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires urgent medical intervention.
Medical interference
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Thermal limits
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Protective goggles
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them shattering into shards.
Serious injuries
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Phone sensors
An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.
Protect data
Do not bring magnets near a purse, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
