Answer 1

A copper colored coil with 5 turns would be surrounded by the strongest magnetic field when current flows through it. Therefore, the correct option is C.

Step-by-step explanation:

The wire that would be surrounded by the strongest magnetic field when current flows through it is a copper colored coil with 5 turns.

When current flows through a coil, it creates a magnetic field. The strength of the magnetic field is determined by the number of turns in the coil. More turns result in a stronger magnetic field. Therefore, a coil with 5 turns would have a stronger magnetic field compared to a coil with 2 turns or a thin copper colored bar.
