Other proposals
Pros as well as cons of rare earth magnets.
Strengths
- Their strength remains stable, and after around ten years it drops only by ~1% (according to research),
- Magnets effectively defend themselves against demagnetization caused by foreign field sources,
- A magnet with a metallic gold surface has an effective appearance,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which increases force concentration,
- 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 potential of accurate shaping and customization to custom needs, neodymium magnets can be modeled in a wide range of forms and dimensions, which increases their versatility,
- Fundamental importance in future technologies – they are used in mass storage devices, electromotive mechanisms, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise 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 those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at room temperature
Key elements affecting lifting force
- Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the flux to be lost into the air.
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Do not overheat magnets
Do not overheat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Threat to navigation
Remember: neodymium magnets generate a field that interferes with precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Flammability
Machining of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Implant safety
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Fragile material
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Data carriers
Data protection: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Serious injuries
Big blocks can crush fingers in a fraction of a second. Do not put your hand between two strong magnets.
Powerful field
Handle with care. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.
Product not for children
Adult use only. Small elements pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
