Advantages as well as disadvantages of rare earth magnets.

Apart from their strong holding force, neodymium magnets have these key benefits:

• They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
• Magnets effectively defend themselves against loss of magnetization caused by external fields,
• A magnet with a smooth silver surface has better aesthetics,
• Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
• Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
• Considering the ability of flexible shaping and customization to specialized requirements, neodymium magnets can be created in a variety of forms and dimensions, which amplifies use scope,
• Universal use in high-tech industry – they serve a role in HDD drives, motor assemblies, advanced medical instruments, as well as multitasking production systems.
• Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Disadvantages of NdFeB magnets:

• At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
• When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
• They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
• Limited possibility of making threads in the magnet and complex forms - preferred is casing - magnetic holder.
• Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products can complicate diagnosis medical when they are in the body.
• Due to neodymium price, their price is relatively high,

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Magnet power is the result of a measurement for the most favorable conditions, including:

• with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
• with a thickness of at least 10 mm
• with a plane perfectly flat
• without any insulating layer between the magnet and steel
• under perpendicular force vector (90-degree angle)
• at ambient temperature approx. 20 degrees Celsius

Impact of factors on magnetic holding capacity in practice

Real force is affected by working environment parameters, such as (from priority):

• Distance – existence of foreign body (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
• Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
• Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
• Plate material – mild steel gives the best results. Alloy steels reduce magnetic permeability and holding force.
• Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
• Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently damage the magnet.

* Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a small distance {between} the magnet and the plate lowers the lifting capacity.
