Electromagnetic fields radiate counter-clockwise in relation to the current flow. For example,
current flows out on a hot conductor and returns on the neutral. This change in opposite current
flow also creates opposing magnetic fields. So, when these two opposing conductors are close
together, the two magnetic fields tend to cancel each other out. This canceling effect diminishes
the circuit's ability to radiate the transmitter's strong signal making it more difficult for the
receiver to detect the signal.
