Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after around 10 years it decreases only by ~1% (theoretically),
- They maintain their magnetic properties even under strong external field,
- In other words, due to the aesthetic layer of nickel, the element looks attractive,
- Magnets are distinguished by impressive magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the capacity to customize to complex applications,
- Wide application in high-tech industry – they find application in hard drives, brushless drives, diagnostic systems, as well as technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- At very 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 suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of making nuts in the magnet and complex shapes - preferred is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can be problematic in diagnostics 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
Highest magnetic holding force – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at temperature room level
Determinants of lifting force in real conditions
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is pure iron steel. Cast iron may attract less.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the holding force.
Powerful field
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Keep away from electronics
GPS units and smartphones are highly sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Keep away from children
Strictly store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are very dangerous.
Risk of cracking
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Keep away from computers
Equipment safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Fire warning
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop working with magnets and wear gloves.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Warning for heart patients
For implant holders: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Finger safety
Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
