Earth's Magnetic Field||Magnetic Materials

The earth's magnetic field is approximately like that of a giant magnetic dipole, whose axis is inclined roughly 20^@ west of the axis of rotation of earth which is the geographic N-S direction. The strength of earth's magnetic field is of the order of 10^-4 tesla . Three magnetic elements of earth are: Magnetic declination (theta) , magnetic inclination or magnetic dip (delta) and horizontal component (H) of earth's magnetic field. Magnetic declination is the small angle between magnetic axis and geographic axis at a place. Magnetic dip at a place is the angle, which the direction of total strength of earth's magnetic field (R) makes with a horizontal line in magnetic meridian. If H is horizontal component and V is vertical component of earth's magnetic field, then H=Rcos delta , V=Rsin delta and R=sqrt(H^2+V^2) . At a place on the surface of earth. H is of the order of 3*3xx10^-5tesla . Magnetic declination is

The earth's magnetic field

The magnitude of earth magnetic field at magnetic equator is 2.8 xx 10^(-5) T . Find magnitude of earth's magnetic field near geomagnetic poles .

Our earth behaves as it has a powerful magnet within it. The value of magnetic field on the surface of earth is a few tenth of gauss (1G = 10^(-4) T) There are three elements of Earth’s magnetism (i) Angle of declination (ii) Angle of dip (iii) Horizontal component of Earth’s magnetic field. In the magnetic meridian of a certain place, the horizontal component of Earth’s magnetic field is 0.6 G and the dip angle is 53^@ . The value of vertical component of earth's magnetic field at this place is
