A dip ciccle shows an apparent dip of 60 degree at a place where the true dip is 45 degree. if the dip circle is rotated throgh 90 degree, what apparent dip will it show? first of all please tell me what is the meaing of apparent dip.how can a dip be apparent? it should always be true dip?

If the plane of the scale of the dip circle is not in the magnetic meridian, then the needle will not indicate the correct direction of earth's magnetic field. The angle made by the needle with the horizontal is known as the magnetic dip.
