Answer 2

The answer will be, “Magnetic effect of electric current increases with increase in the length of the wire.”

Let us take the example of a solenoid.

If we increase the cylindrical turns then it will automatically increase the magnetic effect.

The cylindrical turns can be increased with the increase in length.
