mutual inductance
[ˈmjuːtʃuəl ɪnˈdʌktəns]
nounfemininepl: mutual inductances
indutância mútua
1. The property of an electrical circuit whereby a change in current in one circuit induces an electromotive force (EMF) in another nearby circuit
The mutual inductance between the two coils determines how effectively the magnetic field of one coil couples with the other.
A indutância mútua entre as duas bobinas determina como o campo magnético de uma bobina se acopla efetivamente com a outra.
2. A measure of the magnetic coupling between two circuits, expressed in henries (H)
Engineers calculated the mutual inductance to be 5 millihenries for the transformer design.
Os engenheiros calcularam a indutância mútua como sendo 5 milihenries para o projeto do transformador.
3. The coefficient that quantifies the reciprocal relationship between voltage induction in one coil due to changing current in another coil
The mutual inductance coefficient M is used in Faraday's law to describe electromagnetic induction between coupled circuits.
O coeficiente de indutância mútua M é usado na lei de Faraday para descrever a indução eletromagnética entre circuitos acoplados.
This is primarily a technical term used in electrical engineering and physics, standardized across English-speaking and Portuguese-speaking countries. The concept is fundamental in transformer design and wireless power transfer applications. In both Brazilian and Portuguese educational systems, the term 'indutância mútua' is used consistently in university-level electrical engineering courses and professional practice.
