Explain the definitions of magnetic declination,magnetic dip and horizontal component of earth's magnetic field?
Asked by shrijeet | 23rd Feb, 2013, 02:17: AM
Elements of the earths magnetic field are:
1. Magnetic declination (?): At a point on earth the magnetic meridian makes an angle with the geographic meridian. This angle is known as the magnetic declination or just declination.
2. Angle of dip (?): It is the angle made by the direction of the earths total magnetic field with the horizontal direction.
3. Horizontal component of earths magnetic field (BH): It is the component of earths magnetic field along the horizontal direction.
So the angle of dip is the angle between earths magnetic field i.e. B and the horizontal component i.e. BH.
