# Which of the Statement Given Below Correctly Describes the Magnetic Field Near a Long, Straight Current Carrying Conductor? - Science and Technology 1

MCQ

Which of the statement given below correctly describes the magnetic field near a long, straight current carrying conductor?

#### Options

• The magnetic lines of force are in a plane, perpendicular to the conductor in the form of straight lines.

• The magnetic lines of force are parallel to the conductor on all the sides of conductor.

• The magnetic lines of force are perpendicular to the conductor going radially outword.

• The magnetic lines of force are in concentric circles with the wire as the center, in a plane perpendicular to the conductor.

#### Solution

The correct statement describing the magnetic field near a long, straight current carrying conductor is:
The magnetic lines of force are in concentric circles with the wire as the center, in a plane perpendicular to the conductor.

Concept: Magnetic Field Due to Current in a Loop (Or Circular Coil)
