Pros as well as cons of rare earth magnets.
Strengths
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization induced by external disturbances,
- In other words, due to the shiny finish of gold, the element is aesthetically pleasing,
- Magnetic induction on the working part of the magnet is extremely intense,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the capacity to modify to individual projects,
- Significant place in modern technologies – they are utilized in magnetic memories, drive modules, medical equipment, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- 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 making threads in the magnet and complex shapes - recommended is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- using a sheet made of mild steel, acting as a circuit closing element
- possessing a massiveness of at least 10 mm to avoid saturation
- with an polished touching surface
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Immense force
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Material brittleness
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Machining danger
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Serious injuries
Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Skin irritation risks
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and select coated magnets.
This is not a toy
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep away from children and animals.
Keep away from computers
Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Power loss in heat
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Medical interference
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Threat to navigation
Remember: rare earth magnets generate a field that confuses sensitive sensors. Keep a separation from your phone, tablet, and navigation systems.
