- Description:On February 25, 2025, in Truro, England, UK, @british.culture60 shared a video of a helicopter flying overhead while carrying a large metal circle.

This system is called HeliEM or Heliborne Electromagnetic Survey. The principle of operation is as follows. A current is passed through a loop, creating an electromagnetic field, In response to this field, currents are induced underground, special sensors measure the resulting secondary field, which allows us to understand the structure of underground rocks.
