ADVANTAGES OF RARE EARTH MAGNETS

Rare Earth Magnets: Not as Rare as Their Name Suggests In reality, rare earth magnets are not as rare as their name implies and are often less expensive than other types of magnets. Due to these characteristics, rare earth magnets are frequently used as replacements for magnets with similar properties to perform the same tasks. Here, we outline the excellent advantages of rare earth magnets for your reference.

Rare Earth Magnets – Neodymium Magnets Strength: Neodymium magnets have a magnetic strength that is 7 times greater than Ferrite magnets (ceramic magnets). They have an impressive size-to-strength ratio and excellent temperature stability. Neodymium magnets are the strongest permanent magnets available due to their powerful magnetic fields and resistance to demagnetization.

Durability: These magnets are coated with protective layers such as Nickel, Phosphorus, or Zinc, making them stronger than other permanent magnets like Ferrite or Alnico. Neodymium magnets are available in a wide range of shapes, sizes, and magnetic strengths.

Properties Manufacturing: Manufactured using powder metallurgy techniques.
Chemical Composition: NdFeB.
Brittleness: Very brittle and hard.
Corrosion Resistance: Highest corrosion resistance among all commercial magnets.
Demagnetization Resistance: High resistance to demagnetization.
Cost: Low operating costs and affordable prices.
Temperature Stability: Stable at reasonable temperatures but not suitable for high-temperature applications.

Applications

They are commonly used in many industrial applications where a strong magnet is essential. Some of the applications of rare earth magnets in life include: metal separation, mining, construction, design, printing, generators and other industrial purposes.

Dangers to be aware of when using

Rare earth magnets have very strong magnetic forces, sometimes creating dangers that you cannot see. Neodymium magnets larger than a few cubic centimeters are strong enough to cause damage to body parts when squeezed between two magnets or a magnet with a metal surface, even causing broken bones.

Magnets placed close together can “attack” each other, strong magnets can attract metal objects towards them causing breakage or injury. For children, playing with magnets is really dangerous. There have been cases of children swallowing magnets, leading to injuries that can lead to death. Stronger magnetic fields can be dangerous to mechanical and electronic devices as they can erase magnetic media such as floppy disks, credit cards, magnetize watches, etc.
