Electromagnetic Induction

A metallic cube of side \(15 \mathrm{~cm}\) moving along \(y\)-axis at a uniform velocity of \(2 \mathrm{~ms}^{-1}\). In a region of uniform magnetic field of magnitude \(0.5 \mathrm{~T}\) directed along \(z\)-axis. In equilibrium the potential difference between the faces of higher and lower potential developed because of the motion through the field will be _________ mV.
