  2. Hall effect - Wikipedia

    en.wikipedia.org/wiki/Hall_effect

    One very important feature of the Hall effect is that it differentiates between positive charges moving in one direction and negative charges moving in the opposite. In the diagram above, the Hall effect with a negative charge carrier (the electron) is presented. But consider the same magnetic field and current are applied but the current is ...

  3. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    Hall effect magnetometers (also called tesla meters or gauss meters) use a Hall probe [23] with a Hall element to measure magnetic fields or inspect materials (such as tubing or pipelines) using the principles of magnetic flux leakage. A Hall probe is a device that uses a calibrated Hall effect sensor to directly measure the strength of a ...

    Scaling of the longitudinal and Hall conductivities in a renormalization group flow-diagram of the quantum Hall effect. On the basis of the Renormalization Group Theory of the instanton vacuum one can form a general flow diagram where the topological sectors are represented by attractive fixed points. When scaling the effective system to larger ...
