Question

A metallic cube of side 15 cm is moving along the y-axis at a uniform velocity of 2 m s⁻¹, in a region of uniform magnetic field of magnitude 0.5 T directed along the 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.

Accepted Answer

150. E=vB=2×0.5=1 V m⁻¹ inside the cube. V=E d=1×0.15=0.15 V =150 mV.
