When was the metal detector invented?

Have you ever wondered about the clever invention that helps find hidden treasures like coins, jewelry, or even ancient artifacts buried beneath the ground? It’s called a metal detector! But have you ever asked yourself, “When was the metal detector invented?” Well, let’s dive into the exciting history of this nifty gadget.

The birth of the metal detector marks a pivotal moment in history, intertwining technological innovation with a quest for discovery.

Dove’s exploration of electromagnetic fields laid the groundwork for what would become a transformative invention.

However, it was not until 1881 that Alexander Graham Bell, the renowned inventor of the telephone, took the concept further.

While developing a device to locate a bullet in President James Garfield’s body, Bell inadvertently created the world’s first practical metal detector.

By using an electromagnetic coil, he successfully detected the metallic presence of the bullet.
