Earth magnetic field strength by location

At any location, the Earth's magnetic field can be represented by a three-dimensional vector. A typical procedure for measuring its direction is to use a compass to determine the direction of magnetic North. Its angle relative to true North is the declination (D) or variation. Facing magnetic North, the angle the field makes with the horizontal is the inclination (I) or magnetic dip. The intensi… WebProblem 3) (Measuring the Earth’s magnetic field) For a particular scientific experiment, it is important to be completely isolated from any magnetic field, including the earth's field.
