The true value of dip at a place is `45^@` If the plane of the dip circle is turned through `60^@` from the magnetic meridian, what will be the apparaent value of the dip?

A dip circle is at right angle to the magnetic meridian. What will be its apparanet dip?

What is the maximum and minimum value of dip?

How can the angle of dip be determined without placing the dip circle in the plane of magnetic meridian?

What is the expected value of dip at magnetic poles of the earth?

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 center 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?

A short bar magnet is placed in a horizontal plane with its axis in the magnetic merdian . Null points are found on its equitorial line (i.e., its normal bisector) at 12.5 cm and the earth's magnetic field at the place is 0.38 G the angle of dip is zero. (i) What is the total magnetic field at points on the axis of the magnet located by the same distance (12.5 cm) as the null-points from the centre? (ii) Locate the null points when the magnet is turned around by 180^(@) . Assume that the length of the magnet is negligible as compared to the distance of the null-point from the centre of the magnet.

A dip needle with a circular scale is mounted on a horizontal axis. How can the direction of the magnetic meridian be found with the help of this needle?
