The real angle of dip, if a magnet is suspended at an angle of `30^(@)` to the magnetic meridian and the dip needle makes an angle of `45^(@)` with horizontal, is:

If a magnet is suspended at an angle 30^(@) to the magnetic meridian and in this plane the dip needle makes an angle of 60^(@) with the horizontal. The true value of dip is:

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

If a magnet is suspended at an angle 30∘ to the magnetic meridian and in thisplane the dip needle makes an angle of 60∘ with the horizontal. The true value of dip is

The angle of dip in a plane at an angle of 30^@ with magnetic meridian is 45^@ .The value of true Dip is
