Pros and cons of rare earth magnets.
Advantages
- They retain attractive force for nearly ten years – the drop is just ~1% (in theory),
- They are noted for resistance to demagnetization induced by external disturbances,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnetic induction on the surface of the magnet remains very high,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Due to the possibility of precise shaping and customization to custom needs, NdFeB magnets can be created in a variety of forms and dimensions, which amplifies use scope,
- Versatile presence in modern technologies – they are commonly used in magnetic memories, electric drive systems, diagnostic systems, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, we suggest 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex forms in magnets, we recommend using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- characterized by even structure
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Distance (between the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- 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.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Nickel coating and allergies
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or choose versions in plastic housing.
Dust is flammable
Dust produced during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Powerful field
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often faster than you can move away.
No play value
Strictly keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets connecting inside the body are very dangerous.
Magnetic interference
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Electronic devices
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Pacemakers
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Finger safety
Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and strength.
Shattering risk
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
