today i bought some iron oxide and mixed with water and dispersant, the result is a fluid that is not like ferro fluid i saw in videos but seems magnetic for experiments.
my question is what if there is a way to flip the magnetic field of the molecules with an electric field and magnetic field combined...
So basically my intention is to use the tube just like if it were a tesla coil primary but the secondary is the coils wound on the tubes and they should capture some magnetic field from the material inside the tubes...
i know it seems crazy... but i believe that the combination of magnetic fields de-phased will create a kind of rotating magnetic field which could indeed induce voltage on the secondary coils..
