Pros as well as cons of NdFeB magnets.

In addition to their pulling strength, neodymium magnets provide the following advantages:

• They have stable power, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
• They retain their magnetic properties even under external field action,
• A magnet with a smooth gold surface has better aesthetics,
• The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
• Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures reaching 230°C and above...
• Thanks to freedom in forming and the capacity to modify to unusual requirements,
• Fundamental importance in future technologies – they are used in mass storage devices, electric motors, medical devices, and industrial machines.
• Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems

Cons of neodymium magnets: weaknesses and usage proposals

• They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
• We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest 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 secure oxidation and corrosion.
• Due to limitations in creating threads and complicated forms in magnets, we propose using a housing - magnetic holder.
• Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these magnets can disrupt the diagnostic process medical after entering the body.
• Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Highest magnetic holding force – what it depends on?

The force parameter is a measurement result executed under specific, ideal conditions:

• with the use of a sheet made of special test steel, ensuring maximum field concentration
• possessing a thickness of min. 10 mm to ensure full flux closure
• with an ground contact surface
• without any air gap between the magnet and steel
• under perpendicular force vector (90-degree angle)
• in temp. approx. 20°C

Determinants of practical lifting force of a magnet

Effective lifting capacity impacted by specific conditions, including (from priority):

• Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
• Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
• Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be wasted into the air.
• Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
• Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
• Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.

* Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance {between} the magnet’s surface and the plate reduces the load capacity.
