Rare Earth Neodymium Magnets
Neodymium magnets, often referred to as NdFeB magnets, are the strongest type of permanent magnet commercially available today. They are made from an alloy of neodymium, iron, and boron, which creates an extremely powerful magnetic field relative to the magnet’s size.
Because of their exceptional strength, neodymium magnets are widely used in electronics, engineering, renewable energy, and manufacturing industries.
If you are looking for rare earth neodymium magnets in Australia, these magnets are commonly used in everything from small DIY projects to advanced industrial machinery.
Key Takeaways About Rare Earth Neodymium Magnets
Neodymium magnets are the strongest permanent magnets available.
They are widely used in electronics, motors, sensors, and renewable energy systems.
Their high magnetic strength allows compact designs with powerful performance.
Protective coatings help prevent corrosion and increase durability.
They must be handled carefully due to their powerful magnetic force.
What are n35 Neodymium Magnets?
Neodymium magnets are often classified by magnet grade, such as N35, N42, N50, and N52.
The grade refers to the maximum magnetic energy product of the magnet. In simple terms, the higher the number, the stronger the magnet.
For example:
N35 magnets are common general-purpose magnets used in many products.
N42 and N52 magnets provide stronger magnetic performance for specialised applications.
These magnets are available in many shapes, including:
Disc magnets
Block magnets
Ring magnets
Countersunk magnets
Pot magnets
Pot Thread
Rod magnets
Sphere magnets
Properties of Neodymium Magnets
Extremely Strong Magnetic Force
Neodymium magnets produce an extremely strong magnetic field for their size. This allows engineers and designers to use smaller magnets while maintaining high performance.
This strength makes them ideal for:
Electric motors
Sensors
Magnetic holders
Industrial equipment
Temperature Resistance
Standard neodymium magnets typically operate safely up to about 80°C.
However, specialised grades can tolerate higher temperatures, such as:
120°C
150°C
200°C+
When selecting magnets for high-temperature environments, it is important to choose the correct grade
Corrosion Protection and Coatings
Neodymium magnets can corrode if exposed to moisture or harsh environments. To prevent this, they are commonly coated with protective finishes.
Common coatings include:
Coating | Description |
Nickel-Copper-Nickel | Most common protective coating |
Epoxy | Suitable for humid or marine environments |
Zinc | Cost-effective corrosion protection |
Gold | Decorative or specialised applications |
Choosing the right coating helps improve the magnet’s durability and lifespan.

Large neodymium magnets are widely used in industrial applications.
Examples include:
Magnetic lifting systems
Industrial motors
Conveyor systems
Magnetic separation equipment
Automation and robotics
Their high strength allows heavy objects to be lifted or secured using relatively small magnets.
Safety Precautions for Neodymium Magnets
Because neodymium magnets are extremely powerful, they must be handled carefully.
Handling Tips
Wear protective gloves when handling large magnets
Keep fingers away from magnet contact points
Slide magnets apart instead of pulling them directly
Storage Recommendations
Store magnets in a dry location
Keep them away from electronic devices• Use spacers or padding to prevent magnets from snapping together
First Aid Advice
If fingers become trapped between strong magnets:
Carefully separate the magnets if possible
Clean any wounds immediately
Seek medical assistance if necessary
