Abstract
The interaction of magnetic fields with ions in the flow of NaCl solution has been determined. The
value of pressure and flow velocity was determined based on Bernoulli's law formula. The results
of the test with two experiments, namely the first experiment with a container height of 1 meter and
the second experiment with a container height of 1.5 meters show the potential difference and
resistance values of the known mass concentration of NaCl namely 0 gr/L to 500 gr/L. The
potential difference value with the mass concentration of NaCl 0 gr/L in the first experiment is 7.2
mV smaller than that for the second experiment, which is 22.1 mV, the resistance value in the first
experiment is 25.80 k, greater than that for the second experiment, which is 20.8 k. The value of
this potential difference is called the Hall voltage (VH). where the greater the potential difference,
the flow velocity obtained is inversely proportional to the resistance where the greater the
resistance, the smaller the flow velocity obtained. This result is directly proportional to the current
flowing. The result also shows that for the first experiment's the flow velocity value (V1) is 4.42
m/s and the pressure value (P1) is 9.8 Kpa, while for the second experiment's the flow velocity
(V2) is 5.42 m/s. The pressure value (P2) is 14.7Kpa. Measurement results found that the charged
ions in the magnetic fields deflected due to the influence of the Lorentz force.
