Strong ceramic and alnico magnets are critical for electronic technology and permanent magnetic uses.
You may not realize it, but we depend on magnets for a whole host of industrial, electronic, and consumer uses. While refrigerator magnets are in most every home, most people don’t think about their many technological uses. However, musicians rely on them for their microphones, speakers, and even electric guitar pickups, while the automotive industry uses them for car odometers and lighters. Other common consumer applications include mobile phones and hearing aids.
