In the figure given below, when the key is pressed, a current passes in the wire in the direction from A to B (i.e., from south to north). The north pole of the compass needle will deflect towards:

1. East
2. North
3. South
4. West

In the figure given below, current is passed in a downward direction through a cardboard. The magnetic field lines would be :

1. straight lines
2. concentric circles
3. elliptical lines
4. squares

According to the right hand thumb rule, the thumb points in the direction of …………… and fingers encircle the wire in direction of ……………

1. magnetic field lines, current
2. electric field lines, current
3. current, magnetic field lines
4. none of the above

In the figure given below, the direction of current in the loop is …………… . So, it behaves as a …………… .

1. anticlockwise, south pole
2. anticlockwise, north pole
3. clockwise, north pole
4. clockwise, south pole
