Advantages and disadvantages of rare earth magnets.
Pros
- They retain full power for nearly ten years – the loss is just ~1% (in theory),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic surface of gold, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a unique magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the ability of accurate molding and adaptation to custom requirements, magnetic components can be manufactured in a wide range of shapes and sizes, which makes them more universal,
- Versatile presence in modern industrial fields – they are utilized in HDD drives, motor assemblies, medical equipment, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their force 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We suggest cover - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of high-permeability steel, acting as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Cast iron may attract less.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Crushing risk
Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Choking Hazard
Adult use only. Small elements can be swallowed, leading to serious injuries. Store out of reach of children and animals.
Safe distance
Avoid bringing magnets close to a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
GPS and phone interference
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Allergic reactions
Certain individuals suffer from a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Extended handling can result in dermatitis. We recommend use safety gloves.
Magnet fragility
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Operating temperature
Watch the temperature. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Danger to pacemakers
Individuals with a heart stimulator must maintain an safe separation from magnets. The magnetic field can disrupt the functioning of the implant.
Caution required
Handle magnets consciously. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.
Fire warning
Powder generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
