WebThe Earth's magnetic field strength was measured by Carl Friedrich Gauss in 1832 and has been repeatedly measured since then, showing a relative decay of about 10% over the last 150 years. The Magsat satellite and later satellites have used 3-axis vector magnetometers to probe the 3-D structure of the Earth's magnetic field.

How to Measure the Strength of Magnets Sciencing

WebMagnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature. WebThere are two main types of magnetometers, one is used to observe the net magnetism of an object, called a scalar device, and the other can track the magnetic vector and give the magnetic field strength in a specific direction, called a vector device. Different magnetometers work in different ways. christophe grauwin
