If an electric field passing through a dielectric medium, back into the original medium, is it "back to normal"?

Suppose there is an electric point charge causing an electric field E in a medium with a dielectric constant $epsilon_1$. You can calculate the scalar potential $phi$ at...

Where does the energy go if the current is induced in a perfect conductor?

Let us rotate a closed circuit made of a copper coil in front of a magnet. This will generate an induced current and all the mechanical energy will be converted...

Why doesn't this copy circuit violate the no cloning theorem?

This circuit appears to clone bits. The first picture is the copy circuit which takes |1000> to |1010>. The second picture is the same copy circuit but it's copying hadamard...
