Strengths and weaknesses of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by external interference,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- Magnets exhibit huge magnetic induction on the working surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures reaching 230°C and above...
- Thanks to the option of free shaping and adaptation to specialized needs, magnetic components can be produced in a wide range of shapes and sizes, which expands the range of possible applications,
- Huge importance in electronics industry – they find application in HDD drives, electric drive systems, medical devices, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions
Cons
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in realizing nuts and complicated forms in magnets, we propose using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of structural steel, optimally conducting the magnetic flux
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- without the slightest clearance between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at temperature room level
What influences lifting capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Plate material – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Product not for children
These products are not suitable for play. Swallowing a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates immediate surgery.
Shattering risk
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Handling rules
Handle with care. Rare earth magnets act from a long distance and snap with huge force, often faster than you can move away.
Nickel coating and allergies
Certain individuals suffer from a hypersensitivity to nickel, which is the standard coating for neodymium magnets. Frequent touching may cause skin redness. It is best to wear safety gloves.
Magnetic interference
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Electronic devices
Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Fire risk
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Power loss in heat
Watch the temperature. Heating the magnet to high heat will destroy its properties and pulling force.
Physical harm
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Medical implants
Patients with a ICD should keep an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
