| Aug 22, 2019 at 10:38 | comment | added | Alfred Centauri | @Bzzzz.., the moving rod above can be arbitrarily long, correct? Isn't the analysis the same? Also, I didn't assume that the magnetic force on a mobile electrons does no work, I accept that the magnetic force on a mobile electron is always orthogonal to its velocity by virtue of this equation: $\mathbf{F_B} = q(\mathbf{v}\times\mathbf{B})$ | |

In the above problem you assumed a setup but could you prove the same for a single long conducting wire moving in a uniform magnetic field? | |
