8. In a perfect scenario, you would be able to measure the direction of the current. If the loops are not uniform and not perpendicular to the z-axis on your IOLab unit , you may have a difficult time in determining the direction of the field. Instead, describe the magnetic field generated from a loop of current. You may use words and /or sketches to illustrate , paying attention to the direction of current and the direction of the magnetic field produced. Refer to section 22.9, under 'Magnetic Field Produced by a Current -Carrying Circular Loop' for more
