This study presents the application of Hall Effect sensor for differentiating the combination of liquids based on electrical conductance. Electromagnetic field was generated from wire (AWG 31) bound on high frequency magnetic core namely Toroidal iron power (T131-26) or C-shape Toroidal core. In this study, the electrochemical cell was fixed at 0.09375 cm-1 and there were 10 samples of several liquid types for testing. Hall Effect sensor was designed to place with high frequency magnetic cores bound by 310-turns wire. From experiment using electromagnetic field generated by C-shape Toroidal core, it can be observed that the samples of natural honey from Germany (J) and sugar substitute for diabetics (I) could be distinguished by considering output voltage of Hall Effect sensor (VH) and electrical conductance. The output voltage and the electrical conductance from measurement of natural honey (J) were 3.037 V and 0.941 mS.T, respectively while those from measurement of sugar substitute (I) were 3.030 V and 0.938 mS.T, respectively. Moreover, it can be noted that this methodology could be applied for measuring electrical conductance of several liquid types due to the relationships of output voltage of Hall Effect sensor and electrical conductance of liquid. However, only C-shape Toroidal core was used in this study due to the appropriate generation of electromagnetic field for differentiating both sample liquid types with 1.83% of error for natural honey and 1.51% of error for sugar substitute from 195 times of repetitive measurement.

We propose an approach based on a generalized quantum mechanics to deal with the basic features of the intrinsic spin Hall effect. This can be done by considering two decoupled harmonic oscillators on the noncommutative plane and evaluating the spin Hall conductivity. Focusing on the high frequency regime, we obtain a diagonalized Hamiltonian. After getting the corresponding spectrum, we show that there is a Hall conductivity without an external magnetic field, which is noncommutativity parameter θ-dependent. This allows us to make contact with the spin Hall effect and also give different interpretations. Fixing θ, one can recover three different approaches dealing with the phenomenon.
