WebCapacitive coupling is the transfer of energy within an electrical network or between distant networks by means of displacement current between circuit (s) nodes, induced by the electric field. This coupling can have an intentional or accidental effect. WebInductive Coupling Effects. Magnetic fields, unlike electric fields, are exceedingly difficult to completely shield. Magnetic flux lines do not terminate, but rather loop. Thus, one cannot “stop” a magnetic field, only re-direct its path. A common method for magnetically shielding a sensitive instrument is to encapsulate it in an enclosure ... howard classic
