a first rough separation into “high-frequency” effects, which correspond to radio frequencies beginning at about 100kHz, and “low-frequency” effects. Broadly speaking, low frequency effects operate only by electrical conduction, whereas high-frequency effects may be induced and operate at a distance without a physical connection.
