Strengths as well as weaknesses of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by external interference,
- A magnet with a shiny nickel surface looks better,
- Magnets exhibit impressive magnetic induction on the outer side,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in constructing and the capacity to adapt to client solutions,
- Wide application in innovative solutions – they find application in HDD drives, motor assemblies, medical devices, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these products can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ground touching surface
- with total lack of distance (no coatings)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Warnings
Swallowing risk
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are very dangerous.
Fire risk
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Metal Allergy
Certain individuals suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Extended handling may cause dermatitis. We suggest use safety gloves.
Risk of cracking
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Threat to electronics
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Crushing force
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Respect the power
Be careful. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can react.
Heat warning
Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and strength.
Compass and GPS
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and navigation systems.
Warning for heart patients
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
