Yes exactly, Normally in MHD generators the hot gas is shoot in between the fixed magnetic field, but what if the plasma, in this case fire from the combustion stays in that semi-ring, and the magnets over them spins, could this setup produce electricity? In other words could moving the...

According to the MHD theory, is case of energy production, a magnetic appplying a magnetic field to a moving charge perpendicular to the magnetic field, that could be plasma as well a solution full of ions, and placing two plates, electricity could be produced. Now I have a question, let's say...

Ok I may get this point but so Can you give an explanation to what happens if to an apple's temperature is gamma ray and a radio is shooted at it? Given the fact that the amplitude of both waves are the same. The temperature of the apple raise more with gamma rays or will be the same by using...

We know a way of measuring energy of a electromagnetic wave is the Poynting vector, which is independent of the frequency. But let's say we want to make two different electromagnetic waves, with different wavelengths and so different frequency, but with the same amplitude (so same Poynting...
