Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- Their strength remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
- Magnets very well defend themselves against demagnetization caused by foreign field sources,
- In other words, due to the metallic surface of silver, the element becomes visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the option of free shaping and adaptation to custom solutions, NdFeB magnets can be manufactured in a wide range of forms and dimensions, which increases their versatility,
- Fundamental importance in modern industrial fields – they are commonly used in hard drives, brushless drives, precision medical tools, and industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we advise placing them in strong housings. 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 strength. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a block made of mild steel, effectively closing the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- with total lack of distance (no coatings)
- under axial application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Heat sensitivity
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Electronic devices
Do not bring magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Medical implants
For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Conscious usage
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Crushing force
Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Keep away from electronics
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Adults only
NdFeB magnets are not suitable for play. Eating a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Mechanical processing
Fire warning: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
