The angle of dip at a location in southern India is about `18^(@)`. Would you expect a greater or smaller dip angle in Britain ?

Which is greater? Which is smaller among the given angles?

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north-south direction. Null points are found on the axis of the magnet at 14 cm from the centre of the magnet. The earth's magnetic field at the place is 0.36 G and the angle of dip is zero. What is the total magnetic field on the normal bisector of the magnet at the same distance as the null-point (i.e., 14 cm) from the centre of the magnet ? (At null points, field due to a magnet is equal and opposite to the horizontal component of earth's magnetic field.)

A long straight horizontal cable carries a current of 2.5 A in the direction 10^(@) south of west to 10^(@) north of east. The magnetic meridian of the place happens to be 10^(@) west of the geographic meridian. The earth's magnetic field at the location is 0.33 G, and the angle of dip is zero. Locate the line of neutral points (ignore the thickness of the cable) ? (At neutral points, magnetic field due to a current-carrying cable is equal and opposite to the horizontal component of earth's magnetic field?.

Do oil paper experiments at three different locations and answer the following questions What do you found on those papers dipped in oil?

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north-south direction. Null points are found on the axis of the magnet at 14 cm from the centre of the magnet. The earth's magnetic field at the place is 0.36 G and the angle of dip is zero.If the bar magnet is turned around by 180^(@) , where will the new null points be located ?

The larger of two supplementary angles excceds the smaller by 18^(@) . Find the angles.
