If the currents are in the same direction for a pair of parallel running wires, the currents on the wires are referred as Common Mode currents, ICM. On the other hand, if one of the currents is running in reverse direction (as they should normally do), the currents are referred as Differential Mode currents, IpM. It is essential in analog circuit design to keep track of differential and common mode currents. Referring to the following illustrations, assume that the separation between the wires, d, is 4 mm, the magnetic field observation point, S, is 20 mm away from the right wire, IcM= 5 mA, and IpM= 150 mA. a) Find the ratio of magnetic field density of common mode currents to that of differential mode currents (BCM/BDM) at S. b) Which one should be preferred in a circuit design? why? d d.
