**The Science Behind the Strength
================================!=
To understand how neodymium magnets work, we need to look at the molecular structure of these magnets. The combination of neodymium, iron, and boron creates a complex crystal lattice structure that allows for the magnet’s incredible strength.
The crystal structure is composed of a combination of tetrahedral and octahedral sites, which are home to the magnetic ions. The interaction between these ions creates a strong magnetic field, allowing the magnet to attract and repel other ferromagnetic materials.
How Do Neodymium Magnets Work?
Here’s a step-by-step explanation:
- Magnetic domains: The crystal structure of the neodymium magnet is composed of small regions called magnetic domains. These domains are aligned in the same direction, creating a strong magnetic field.
- Rare-earth elements: The neodymium, iron, and boron elements in the magnet’s structure contribute to the magnet’s strength. Neodymium is responsible for the strong magnetic field, while iron and boron help to reduce the magnet’s remanence.
- Unpaired electrons: The unpaired electrons in the neodymium ions create a net magnetic moment, which is responsible for the magnet’s magnetic field.
