👉 In the context of electrical engineering and electromagnetics, "subnodal" refers to a specific type of node in an electromagnetic field. This term is used when discussing the behavior of electric currents and magnetic fields within a conductor or circuit. In simple terms, a subnode is a region where a current or voltage source can be located without affecting another component within that area. For example, if there are two conductors connected by a current loop, one node (the "subnode") would
