No force acts on a current carrying conductor when it is placed-

Explanation

The correct answer is that no force acts on a current-carrying conductor when it is parallel to the magnetic field. This is because the force experienced by a current-carrying conductor in a magnetic field is given by the equation F = I * L * B * sin(θ), where θ is the angle between the direction of current and the magnetic field. When the conductor is parallel to the field, θ is 0°, and sin(0°) is 0, resulting in no force exerted on the conductor.Option A is incorrect because a conductor perpendicular to the magnetic field experiences the maximum force, as sin(90°) is 1. Option C is incorrect because a conductor far away from the magnetic field is not subjected to the field's influence and hence does not experience any force. Option D is incorrect because simply being inside a magnetic field does not guarantee that no force acts on the conductor; the orientation matters.
