Abstract

"SISTEMA LóGICO MAGNéTICO". Um sistema de acionamento e um método para se efetuar a propagação de uma parede de domínio magnético através de um conduto ferromagnético são descritos, onde uma corrente elétrica oscilante é passada através do conduto a partir de uma fonte de suprimento de corrente oscilante através de pelo menos dois contatos elétricos adaptados para a feitura de uma conexão elétrica com pelo menos dois pontos espaçados no conduto. Um conduto ferromagnético é descrito, compreendendo um elemento ferromagnético alongado formado como uma trilha contínua de material magnético capaz de sustentar e propagar uma parede de domínio, e um sistema de acionamento como esse em um arranjo serial, preferencialmente sendo ainda adaptado para servir como um elemento lógico magnético pela provisão de nós e/ou mudanças direcionais, como resultado do que funções lógicas podem ser processadas.
