Neodymium Magnet vs. Regular Magnet: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 12, 2023
Neodymium magnets are powerful, rare-earth magnets made from an alloy of neodymium, iron, and boron, whereas regular magnets are less potent, typically made from iron, nickel, or cobalt.
Key Differences
Neodymium magnets, composed of neodymium, iron, and boron, are known for their exceptional magnetic strength and are widely used in high-performance applications. While, regular magnets, typically made of materials like ferrite or alnico (aluminum, nickel, cobalt), are less powerful and more commonly found in everyday items.
The magnetic field of neodymium magnets is much stronger than that of regular magnets, making them ideal for applications where space is limited but strong magnetic force is required. In contrast, regular magnets, though weaker, are sufficient for simple applications like refrigerator magnets or educational tools.
In terms of durability, neodymium magnets are more prone to corrosion and require protective coatings, whereas regular magnets, especially ceramic ones, are more resistant to corrosion and can be used without such coatings.
Neodymium magnets have a higher coercivity, meaning they can maintain their magnetic properties at higher temperatures compared to regular magnets. However, regular magnets are more tolerant of extreme temperatures and environments, though they have a lower magnetic strength.
Cost-wise, neodymium magnets are more expensive due to their rare-earth composition and manufacturing process. Regular magnets, being made from more abundant materials, are generally cheaper and more accessible for everyday uses.
