ስለ Neodymium

Neodymium is a soft, silvery metal and the second most abundant rare earth after cerium. NdFeB magnets are the strongest type of permanent magnet commercially available and essential for modern technology.

ፕሮግራሞች

Powerful permanent magnets (hard drives, headphones, electric motors, wind turbines), lasers, and glass coloring.

ሐቅ

Neodymium magnets are so powerful that two large ones can crush fingers, and they are essential for EV motors and wind turbines.
