Pls help ASAP A Hall effect experiment is performed on a n type semiconductor barwhose dimensions are: 2.9 mm along x-axis, 6.2 mm along y-axis, and 17mm along z-axis. A 24 mA electric current flows in the +z directionwhen a 5.0 V battery connected to the bar. The bar is placed in amagnetic field along y axis, and the Hall electric field is 15 V/m pointingin the +x direction. The current carrier concentration in the bar is9.5x1014 cm-3. Determine the direction and magnitude of the magneticfield in units of Tesla. Enter a positive value if the magnetic field ispointing in the +y direction. Enter a negative value if the magnetic fieldis pointing in the -y direction.

Electric field E=15 V/m in x-direction, carrier concentration n=9.54*1014 /cm3=9.4*1023 /m3, Current…
