Transport control in bismuth by tuning its charge and thermal properties via the orientation of an applied external magnetic field is proposed. It is demonstrated that the direction dependent polarization effects of the magnetic field can remove the Dirac valley degeneracy in bismuth electronic structure suggesting that valleytronics is a possible way to control thermoelectricity.
