These experiments will help system designers understand the impact PCB layout techniques have on controlling magnetic coupling in their design. The Magnetic Field Evaluation Board supports measurement of inductive (magnetic) trace-to-loop and loop-to-loop coupling, with and without shielding by planes. Some experiments examine strong horizontal between layer loop-to-loop coupling, where shielding effects are easily demonstrated. Other experiments examine typical PCB trace configurations. where loop areas are much smaller and effects of distance are easily demonstrated. Limited by Gain Bandwidth of the on-board common-base Gain=100 signal booster [needs 911], experiments are run from 1 kHz to 1 OMHz, to demonstrate how inductive coupling is dependent on frequency. With 5VAC input (yielding 0.1 amp peak-to-peak into 50 ohm load]. amplifier output amplitudes are .002Vto 2 volts.
