Salt water magnetic fluid generator? I thought about it when I was in high school and did a simple experiment, but the experiment failed. I asked the professor later, but I didn't get the answer I wanted. Now let me give you this analysis (from an electrochemical point of view), which can resolve your doubts:
The ionic liquid mentioned by your teacher should not be an ionic solution. Ionic solutions are not charged (solutions containing chloride and ions). The sodium ions in the solution are under the action of the electric field. Only when the electric field is added are the anions and cations separated by the electric field. Under normal circumstances, they exist as hydrated molecules), hence movement. of the solution alone through the magnetic field is not affected by the electric field. The Lenz force acts toward both poles to produce voltage.
If it is a gas or liquid plasma molten at high temperature, it is different. The electrons inside are already in a released and independent state. As long as they pass through the magnetic field at high speed. will be polarized towards both poles and will generate voltage.
Plasma refers to a special state of matter that contains equal amounts of positive and negative ions after the separation of atoms into electrons and nuclei.
Generation can be generated when plasma moves in a magnetic field. This method has a simple principle and equipment, and is easy to accelerate and deviate. However, the plasma must be separated at high altitudes, which is technically difficult.
