Pros and cons of rare earth magnets.
Advantages
- They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
- Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
- By using a shiny layer of nickel, the element has an modern look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of precise forming and adapting to atypical needs,
- Huge importance in future technologies – they are commonly used in mass storage devices, electric drive systems, medical devices, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in small systems
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose 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
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- using a sheet made of low-carbon steel, serving as a ideal flux conductor
- whose transverse dimension reaches at least 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Metal type – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, whereas under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness happens, immediately stop handling magnets and wear gloves.
Electronic hazard
Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, timepieces).
Magnets are brittle
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
ICD Warning
Individuals with a heart stimulator must keep an safe separation from magnets. The magnetism can stop the operation of the implant.
Powerful field
Be careful. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can react.
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Crushing force
Large magnets can break fingers instantly. Never place your hand between two attracting surfaces.
No play value
Neodymium magnets are not toys. Eating multiple magnets can lead to them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.
Operating temperature
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
GPS and phone interference
Be aware: rare earth magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, device, and GPS.
