Advantages and disadvantages of neodymium magnets.
Advantages
- Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by external field sources,
- Thanks to the shimmering finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Magnetic induction on the surface of the magnet is impressive,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the ability of precise forming and adaptation to custom solutions, NdFeB magnets can be created in a wide range of geometric configurations, which amplifies use scope,
- Fundamental importance in future technologies – they serve a role in computer drives, electric drive systems, precision medical tools, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and 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 rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, small components of these magnets are able to complicate diagnosis medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a plate made of high-permeability steel, serving as a circuit closing element
- whose thickness reaches at least 10 mm
- with an polished contact surface
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Dust explosion hazard
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
Power loss in heat
Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Fragile material
Despite the nickel coating, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and select coated magnets.
Crushing force
Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Magnetic media
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Keep away from children
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Keep out of reach of kids and pets.
Do not underestimate power
Be careful. Rare earth magnets attract from a distance and connect with huge force, often faster than you can react.
ICD Warning
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Magnetic interference
Remember: rare earth magnets generate a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
