Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- Their strength remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic layer of silver, the element gains visual value,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- 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 forming as well as optimizing to complex conditions,
- Versatile presence in future technologies – they are commonly used in computer drives, electric motors, advanced medical instruments, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience 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 usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We recommend cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of structural steel, optimally conducting the magnetic field
- with a thickness of at least 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Plate thickness – too thin steel does not accept the full field, causing part of the power to be wasted to the other side.
- Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Warning for heart patients
People with a ICD have to keep an safe separation from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Heat warning
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Precision electronics
Be aware: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your phone, device, and GPS.
Bodily injuries
Pinching hazard: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Powerful field
Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can react.
Fire warning
Powder produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Beware of splinters
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Keep away from computers
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Swallowing risk
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
