In this paper are presented some effects observed on induced electromotive force (emf) in transformers built with planar coils. Several experiments were realized crossing the planar coils with different turn number, exciting primary with square wave and observing responses on secondary. The results obtained are analyzed through transfer function of the transformer, showing important results about systems excited with square waves, which can be used in several researches as pulse transformers.
