Pros as well as cons of Nd2Fe14B magnets.
Benefits
- Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
- They feature excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- Considering the option of precise forming and adaptation to unique projects, NdFeB magnets can be produced in a broad palette of shapes and sizes, which increases their versatility,
- Fundamental importance in modern industrial fields – they are commonly used in HDD drives, electric motors, medical devices, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize 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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these devices can be problematic in diagnostics 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
Maximum lifting capacity of the magnet – what contributes to it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section minimum 10 mm
- with a plane free of scratches
- without any clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- in stable room temperature
Determinants of lifting force in real conditions
- Distance – existence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Dust explosion hazard
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Allergy Warning
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact or select encased magnets.
Implant safety
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Crushing force
Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Cards and drives
Do not bring magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Immense force
Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Keep away from electronics
Be aware: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and GPS.
Adults only
Adult use only. Tiny parts can be swallowed, causing serious injuries. Store away from kids and pets.
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
