mutual induction

Counter-induction is an induction effect that counteracts the original inductance. It is an externally induced magnetic field whose induction voltage as a counter-induction voltage does not allow the current flow in the original inductance to increase as quickly.

Counter-induction occurs in inductive coupling between current-carrying conductors, coils and in transformers. In this case, the primary inductance generates a mutual induction voltage in the secondary inductance, which is opposite to the actual induction voltage and counteracts the magnetic field in the primary inductance. It is an undesirable effect that affects switch-on and switch-off operations and causes crosstalk in current-carrying conductors.
