ferroresonance
ferroresonance n. 
/ˌfɛrə(ʊ)ˈrɛzn̩əns/, /ˌfɛroʊˈrɛzn̩əns/ [after French ferro-résonance (P. Boucherot 1920, in Rev. gen. de l’électricité 22 May 678/2, the paper summarized in quot. 1920); the phenomenon is so called because it was first observed in iron-sheathed cables] a type of resonance in which there is an interaction between a non-linear inductance (typically, that of an iron-core component) and the capacitance of a circuit.

1920 Abstr. Papers Sci. Trans. & Periodicals No. 5. 112 He [sc. P. Boucherot] gives the name of ‘ferro-resonance’ to the effect produced when the self-induction is variable owing to the presence of iron sheathing.
1956 T. E. Ivall Electronic Computers viii. 103 Ferro-resonance is the condition which exists when a saturable inductor and a capacitor resonate so that the increased current at resonance keeps the inductor core saturated.
2005 Jrnl. Materials Processing Technol. 161 157/1 Ferroresonance can occur when a de-energized phase of a no-load transformer is suddenly energized through capacitance coupling with the other phases.
