Advantages as well as disadvantages of neodymium magnets.
Advantages
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external field sources,
- In other words, due to the shiny finish of nickel, the element becomes visually attractive,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of precise forming and customization to specialized solutions, neodymium magnets can be created in a broad palette of geometric configurations, which expands the range of possible applications,
- Huge importance in high-tech industry – they are utilized in data components, electric motors, diagnostic systems, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in realizing threads and complex forms in magnets, we recommend using cover - magnetic mount.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- characterized by lack of roughness
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Lifting capacity in practice – influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the holding force.
Warnings
Medical interference
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Power loss in heat
Keep cool. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Crushing force
Pinching hazard: The pulling power is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Cards and drives
Do not bring magnets near a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Keep away from electronics
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
This is not a toy
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store out of reach of kids and pets.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease working with magnets and wear gloves.
Do not underestimate power
Handle with care. Neodymium magnets act from a distance and connect with massive power, often faster than you can react.
Fire warning
Dust generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
