Strengths as well as weaknesses of rare earth magnets.
Advantages
- Their magnetic field is durable, and after approximately 10 years it drops only by ~1% (theoretically),
- Neodymium magnets prove to be exceptionally resistant to demagnetization caused by magnetic disturbances,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are characterized by huge magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of accurate forming and customization to specialized requirements, magnetic components can be modeled in a broad palette of geometric configurations, which makes them more universal,
- Universal use in advanced technology sectors – they are used in HDD drives, electric motors, advanced medical instruments, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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 when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a plate made of high-permeability steel, acting as a circuit closing element
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- with total lack of distance (without impurities)
- during pulling in a direction perpendicular to the plane
- at room temperature
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (rust, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Allergy Warning
Certain individuals suffer from a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact can result in an allergic reaction. We recommend use protective gloves.
Electronic hazard
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Danger to pacemakers
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Keep away from children
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are fatal.
Threat to navigation
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Protective goggles
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them shattering into small pieces.
Respect the power
Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often faster than you can react.
Crushing force
Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Thermal limits
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Machining danger
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
