Strengths as well as weaknesses of neodymium magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets are remarkably resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the shiny finish, the plating of nickel, gold, or silver-plated gives an modern appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of accurate forming and adaptation to specialized solutions, NdFeB magnets can be modeled in a broad palette of geometric configurations, which expands the range of possible applications,
- Universal use in future technologies – they are used in hard drives, brushless drives, diagnostic systems, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in miniature devices
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- using a plate made of low-carbon steel, functioning as a magnetic yoke
- with a thickness minimum 10 mm
- with a surface perfectly flat
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Steel type – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces 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 holding force.
Safety rules for work with neodymium magnets
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Precision electronics
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Electronic devices
Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Handling rules
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Choking Hazard
Always keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Skin irritation risks
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or select encased magnets.
Dust explosion hazard
Dust created during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Crushing force
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Danger to pacemakers
People with a heart stimulator should keep an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Demagnetization risk
Watch the temperature. Heating the magnet to high heat will destroy its properties and pulling force.
