Question

3. [MAGN.04: Ampere's Law] A long, 2.0 cm thick cable carries 6.0 A of current in the +z direction (into the page in this picture). What are the magnetic fields at radial distances of 0.5 cm and 2.0 cm from the middle of the cable? Give both the magnitudes and the sense (clockwise or counterclockwise from the perspective of this drawing). 0.5 cm 2.0 cm 2.0 cm

PLEASE HELP MAKE SURE ANSWER IS CORRECT !!! ASAP
