If you place 2 sliders in touch with the opposite edges of the wire, and say the sliders are stationary relative to the magnetic field, then a voltage is generated between the sliders. If there are no sliders and the B field is not uniform over the length of this wire, then there will be Eddy...
No you don’t. (sorry for the late reply, hopefully your still about)
If you have a single conducting plate and give it a charge Q/2 then this charge will be distributed over the 2 surfaces. In absence of any other charges, the field lines will be extended into space. However you could just as...
