Abstract

"DISPOSITIVO INDUTIVO CONTROLáVEL". A presente invenção refere-se a um indutor controlável, compreendendo os primeiro e segundo elementos de tubo coaxiais e concêntricos, em que os ditos elementos são conectados um ao outro em ambas as extremidades por meio de acopladores de extremidades magnéticos, um primeiro enrolamento é feito em torno de ambos os ditos elementos, e um segundo enrolamento é feito em torno de pelo menos um dos ditos elementos, em que o eixo geométrico de enrolamento do primeiro elemento é perpendicular aos eixos geométricos dos elementos, e o eixo geométrico de enrolamento do segundo enrolamento coincide com os eixos geométricos dos elementos, caracterizado pelo fato de que os ditos primeiro e segundo elementos magnéticos são feitos de um material magnético anisotrópico de tal forma que a permeabilidade magnética na direção de um campo magnético introduzido pelo primeiro dos ditos enrolamentos é significativamente maior que a permeabilidade magnética na direção de um campo magnético introduzido pelo segundo dos ditos enrolamentos.
