    Question

    Lines of the magnetic field around a current-carrying straight conductor will be

    1. Straight lines parallel to conductor
    2. Circular in a plane parallel to conductor
    3. Circular in a plane perpendicular to the conductor
    4. Straight perpendicular to the conductor

    hintHint:

    Magnetic field lines are the lines in a magnetic field the tangent of which at any point will give the field direction at that point and its density gives the magnitude of the field.

    The correct answer is: Circular in a plane perpendicular to the conductor

      • Magnetic field lines are the lines in a magnetic field the tangent of which at any point will give the field direction at that point and its density gives the magnitude of the field.
      • The magnetic field lines around a straight current-carrying conductor are concentric circles with centre at the conductor.
