Strengths as well as weaknesses of rare earth magnets.
Benefits
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- In other words, due to the glossy layer of silver, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of exact creating and optimizing to concrete requirements,
- Huge importance in electronics industry – they are commonly used in magnetic memories, brushless drives, precision medical tools, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices
Limitations
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of producing nuts in the magnet and complicated shapes - recommended is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Maximum magnetic pulling force – what contributes to it?
- using a plate made of mild steel, serving as a circuit closing element
- with a thickness minimum 10 mm
- characterized by even structure
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at temperature room level
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast 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.
Safety rules for work with NdFeB magnets
Pinching danger
Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Do not drill into magnets
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Health Danger
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Magnetic interference
An intense magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.
Data carriers
Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).
Choking Hazard
Absolutely keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are tragic.
Fragile material
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Permanent damage
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Powerful field
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
