Advantages and disadvantages of neodymium magnets.
Pros
- They do not lose strength, even over nearly ten years – the reduction in lifting capacity is only ~1% (based on measurements),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic layer of nickel, the element looks attractive,
- Magnetic induction on the working layer of the magnet turns out to be very high,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- In view of the possibility of precise molding and adaptation to specialized projects, NdFeB magnets can be modeled in a variety of forms and dimensions, which increases their versatility,
- Wide application in electronics industry – they are commonly used in computer drives, drive modules, precision medical tools, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small elements of these magnets can complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Highest magnetic holding force – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ground contact surface
- with zero gap (no paint)
- under axial force direction (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of any layer (rust, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Conscious usage
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Keep away from children
Strictly store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Magnets are brittle
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Keep away from electronics
Note: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
Data carriers
Intense magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Hand protection
Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Metal Allergy
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.
Do not overheat magnets
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Medical implants
Individuals with a ICD have to maintain an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.
Flammability
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
