WebThe magnetic field at point P has been determined in Equation 12.15. Since the currents are flowing in opposite directions, the net magnetic field is the difference between the two fields generated by the coils. Using the given quantities in the problem, the net magnetic field is then calculated. Solution WebThese coils are short, fat (large-diameter) solenoids. As in any solenoid, the magnetic field lines loop around the coil, and within the coil and next to it along its length, the field lines are parallel to the axis of the coil.
