SUMMARY
The copper-coil electronic component discussed is identified as an inductor, which functions by opposing changes in current. When paired with capacitors, it forms a resonant tank circuit capable of oscillating at specific frequencies. The presence of ceramic capacitors suggests its application in wireless receivers, transmitters, or filters. Additionally, if the coil contains a variable inductance slug made of powdered iron or ferrite, it can be adjusted using an insulated screwdriver, indicating further functionality.

That's an inductor. It works by opposing a change in current, and if used in conjunction with capacitors it works as a resonant tank which can oscillate at some frequency.
Given a lot of ceramic caps around the coil, it would indicate that the circuit is some kind of a wireless receiver, transmitter, or a filter.

It is a coil of wire.
It may have a "slug" of powdered Iron or Ferrite inside it on a screw thread. This would make its inductance variable. This would look grey or black and would have a slot or a hex hole in it for use with an insulated screwdriver.
If it has other windings that are not visible in the picture, it would be a transformer.
