This is going to be a long walk. Flux lines are another way of depicting direction. Instead of a regularly spaced grid of arrows, we draw a path that follows the magnetic field direction, always progressing in the direction of the local field. ...
In physics, flux is a measure of the number of electric or magnetic field lines passing through a surface in a given amount time. Field lines provide a mechanism for visualizing the magnitude and direction of the field being measured. They are imaginary lines that follow different patterns, dep...
A fluxgate magnetometer is a sensor capable of measuring the orientation and intensity of magnetic flux lines. Although traditionally used in geological prospecting, underwater navigation and land navigation, fluxgate magnetometers are also used in robotic space probes while analyzing magnetic fields of ...

Magnetic field strength is the intensity of a magnetic field, usually measured in teslas. The Earth's magnetic field strength is...
Coils are the simple magnetic sensors that can detect changes of the magnetic flux density. As shown in Figure 1, when a magnet is brought close to the coil, the magnetic flux density in the coil increases by ΔB. Then, an induced electromotive force/induced current that generates a magneti...
