Pros and cons of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
- By applying a decorative coating of gold, the element acquires an elegant look,
- Magnets have extremely high magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of individual creating and adapting to atypical requirements,
- Key role in high-tech industry – they are used in mass storage devices, electric drive systems, diagnostic systems, and complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of producing nuts in the magnet and complicated forms - recommended is casing - magnet mounting.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these devices are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Crushing risk
Pinching hazard: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
ICD Warning
Individuals with a ICD must maintain an absolute distance from magnets. The magnetic field can stop the operation of the implant.
Danger to the youngest
NdFeB magnets are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Safe operation
Handle magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their force.
Safe distance
Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Allergic reactions
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact or select versions in plastic housing.
Flammability
Combustion risk: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Power loss in heat
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Eye protection
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them breaking into shards.
