Pros as well as cons of NdFeB magnets.

Apart from their notable power, neodymium magnets have these key benefits:

• Their power is durable, and after around 10 years it drops only by ~1% (according to research),
• They are extremely resistant to demagnetization induced by external field influence,
• Thanks to the reflective finish, the layer of nickel, gold-plated, or silver-plated gives an modern appearance,
• They are known for high magnetic induction at the operating surface, which increases their power,
• Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
• Thanks to versatility in shaping and the ability to customize to unusual requirements,
• Wide application in modern industrial fields – they find application in magnetic memories, electric motors, medical devices, and technologically advanced constructions.
• Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons of neodymium magnets: weaknesses and usage proposals

• At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
• We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
• When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
• Limited possibility of creating nuts in the magnet and complicated forms - preferred is cover - magnet mounting.
• Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these products are able to be problematic in diagnostics medical when they are in the body.
• High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Maximum magnetic pulling force – what contributes to it?

Information about lifting capacity was defined for the most favorable conditions, including:

• using a plate made of low-carbon steel, functioning as a magnetic yoke
• with a cross-section minimum 10 mm
• with a surface perfectly flat
• with direct contact (no paint)
• for force applied at a right angle (pull-off, not shear)
• at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

During everyday use, the actual lifting capacity results from many variables, listed from the most important:

• Gap (between the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
• Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
• Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
• Metal type – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
• Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
• Thermal environment – heating the magnet results in weakening of force. It is worth remembering the maximum operating temperature for a given model.

* Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap {between} the magnet and the plate decreases the load capacity.
