    With the help of an activity, explain the method of inducing electric current in a coil with the help of a magnet. State the rule used to find the direction of electric current thus generated in the coil. A current through a horizontal power line flows in west to east direction. (i) What is the direction of magnetic field at a point directly above it and a point directly below it? (ii) Name the rule used to determine (a) The direction of force when a current carrying wire is placed in a strong magnetic field. (b) Magnetic field in a current carrying conductor.

    Draw the magnetic field lines (including field directions) of the magnetic field due to a circular coil of current. Name any two factors on which the magnitude of the magnetic field due to this coil depends.

    Describe an activity to know the direction of magnetic field produced by a current-carrying straight conductor. Also show that direction of magnetic field is reversed on reversing the direction of current.

    Plot a magnetic field due to a circular coil carrying current and explain the law used to find the direction of magnetic field at the centre of circular coil carrying current.
