    Q2:

    Assertion (A) : The strength of the magnetic field produced at the centre of a current carrying circular coil increases on increasing the number of turns in it. Reason (R) : The current in each circular turn has the same direction and the magnetic field due to each turn then just adds up.

    Q5:

    As shown in the diagram an aluminium rod 'AB' is suspended horizontally between the two poles of a strong horse show magnet in such a way that the axis of rod is horizontal and the direction of the magnetic field is vertically upward. The rod is connected in series with a battery and a key.

    Important question of Class 10

    State giving reasons: (a) What is observed when a current is passed through the aluminium rod from end B to end A ? (b) What change is observed in a situation in which the axis of the rod 'AB' is moved and aligned parallel to the magnetic field and current is passed in the rod in the same direction ?
