Question

Concentric circles representing the magnetic field around a current-carrying striaght wire become larger and larger as we move away from it.

Answer 1

Answer:

Yes, it is true.

Explanation:

As you move away from the current-carrying straight wire (centre of concentric circles) the radius increases and strength of the magnetic field weakens.

To show the weakness of the strength of magnetic field, concentric circles become larger and larger.
