Draw a labelled diagram to show the pattern of magnetic field lines produced due to a current carrying straight conductor. Mark on it the direction of current in the conductor and the direction of magnetic field lines.
Solution
(a) Diagram showing magnetic field lines around a current-carrying straight conductor in a circuit with variable resistance, ammeter and battery (Fig.12.6(a), NCERT page 199). Diagram: Directions of current and magnetic field.
