Pros as well as cons of neodymium magnets.
Pros
- They do not lose magnetism, even during approximately 10 years – the drop in power is only ~1% (theoretically),
- They show high resistance to demagnetization induced by external disturbances,
- Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an professional appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- 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...
- Thanks to flexibility in shaping and the capacity to customize to complex applications,
- Huge importance in advanced technology sectors – they are used in mass storage devices, brushless drives, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in producing threads and complex forms in magnets, we recommend using cover - magnetic mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an polished contact surface
- without the slightest clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under 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 lifting capacity.
Safe handling of NdFeB magnets
Respect the power
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Pacemakers
Patients with a ICD must keep an large gap from magnets. The magnetism can disrupt the operation of the implant.
Cards and drives
Do not bring magnets near a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Do not overheat magnets
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, immediately stop working with magnets and use protective gear.
Keep away from electronics
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Combustion hazard
Powder generated during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
Magnet fragility
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them cracking into shards.
Serious injuries
Pinching hazard: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
No play value
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Keep away from kids and pets.
