Pros as well as cons of NdFeB magnets.

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

• They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
• Neodymium magnets are extremely resistant to demagnetization caused by magnetic disturbances,
• By using a smooth layer of nickel, the element has an proper look,
• Magnetic induction on the surface of the magnet turns out to be exceptional,
• Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
• Possibility of exact modeling and adjusting to specific requirements,
• Fundamental importance in future technologies – they find application in data components, electromotive mechanisms, medical devices, also technologically advanced constructions.
• Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages of neodymium magnets:

• Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
• When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
• They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
• Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic mechanism.
• Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these magnets can complicate diagnosis medical in case of swallowing.
• High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities

Optimal lifting capacity of a neodymium magnet – what affects it?

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

• using a base made of mild steel, acting as a magnetic yoke
• possessing a thickness of minimum 10 mm to avoid saturation
• characterized by even structure
• with direct contact (without impurities)
• under vertical force vector (90-degree angle)
• in stable room temperature

Key elements affecting lifting force

During everyday use, the real power results from several key aspects, ranked from most significant:

• Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
• Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
• Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped into the air.
• Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
• Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
• Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.

* Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap {between} the magnet’s surface and the plate decreases the holding force.
