Ques 1: What are magnetic elements of earth?
Ans: These are the physical quantities that evaluate the intensity of the earth’s magnetic field completely in magnitude as well as in direction. There are mainly three types of magnetic elements
Magnetic Declination-Magnetic Elements Of Earth -12
Magnetic declination is one of the magnetic elements of earth at a place is defined as the angle that the geometric meridian makes with the magnetic meridian and is denoted by theta.
Magnetic Inclination or Dip:
Magnetic inclination at a place is defined as the angle that the direction of earth’s total magnetic field B makes with the direction of horizontal component of earth’s magnetic field and is denoted by delta. Thus, as per the fig. given here
Horizontal Component of earth’s magnetic field-Magnetic Elements Of Earth -12
This is defined as component of earth’s magnetic field along the horizontal direction and is denoted by BH . These magnetic elements of earth are required for the study magnetic field of earth completely.
