Answer 2

Answer:

$\huge\green{Here's your answer}$

The concentric circles become larger as we move away from the conductor because as the distance increases from the current carrying conductor the strength of the magnetic field fades away. Thus, the strength of the magnetic field is inversely proportional to the distance from the current carrying conductor
