PleasA closed planer wire loop of area `A` and arbitrary shape is placed in a uniforms magnetic field of magnitude `B`, with iits plane perpendicualr to magnetic field. The resistance of the wire loop is `R`. The loop is now turned upside down by `180^(@)` so that its plane again becomes perpendicular to the magentic field. The total charge that must have flowed through the wire ring in the process is
