Abstract

"MEDINDO CORRENTE ATRAVéS DE UM CONDUTOR ELéTRICO". A invenção refere-se a uma bobina que inclui uma primeira porção (415), uma segunda porção (420), uma terceira porção (427) e uma quarta porção (428). A primeira porção (415) está enrolada em uma primeira direção ao redor de um primeiro núcleo (435) e a segunda porção (420) está enrolada na primeira direção ao redor de um segundo núcleo (440). A terceira porção (427) está enrolada em uma segunda direção que é diferente da primeira direção ao redor de um terceiro núcleo (445) de tal modo que a terceira porção (427) fique desacoplada das primeira e segunda porções (415, 420). Além disso, a quarta porção (428) está enrolada na segunda direção ao redor de um quarto núcleo (450) e desacoplada das primeira e segunda porções (415, 420). Uma área interna é formada pela disposição das porções e uma voltagem é induzida na bobina se um condutor elétrico for colocado na área interna.
