A Hall effect experiment is performed on a n type semiconductor bar whose dimensions are: 2.9 mm along x-axis, 6.2 mm along y-axis, and 17 mm along z-axis. A 24 mA electric current flows in the +z direction when a 5.0 V battery connected to the bar. The bar is placed in a magnetic field along y axis, and the Hall electric field is 15 V/m pointing in the +x direction. The current carrier concentration in the bar is 9.5x1014 cm-³. Determine the direction and magnitude of the magnetic field in units of Tesla. Enter a positive value if the magnetic field is pointing in the +y direction. Enter a negative value if the magnetic field is pointing in the -y direction.
