The needle of a dip circle when placed at a geomagnetic pole stays along 

The angle between the magnetic meridian and geo meridian is known as 

The earth’s magnetic field always has a vertical component except at,

If a magnet is suspended at an angle 30° to the magnetic meridian, the dip needle makes an angle of 60° with the horizontal. What is the true value of dip?

If a magnet is suspended at an angle of 30° to the magnetic meridian, the dip needle makes an angle of 45° with the horizontal. The real dip is:

Choose the right one from the following. A deflection magnetometer can be used for measuring 

The lines of force due to earth’s horizontal magnetic field are 

If the earth’s horizontal and vertical components are equal at a certain point, the angle of dip is,

The angle θ between the geographic and magnetic meridian at a place is 58' and the angle made by the earth’s resultant with the horizontal is 30^o. What is the angle of declination?

At which place earth’s magnetism becomes horizontal?
