Abstract

resumo patente de invenção: "dispositivo de determinação de propriedade magnética e método de determinação de propriedade magnética". a invenção refere-se a um dispositivo de determinação de propriedade magnética para detectar e determinar uma propriedade magnética de uma substância magnética incluída em uma folha de papel que é carregada em uma trajetória de carregamento que é configurado por: uma unidade de detecção magnética que gera, na trajetória de carregamento, um campo magnético de polarização, sendo que a direção de campo magnético do qual é uma direção que forma um ângulo predeterminado com uma superfície de carregamento da folha de papel e detecta a quantidade magnética da substância magnética pela alteração do campo magnético de polarização; e uma unidade de magnetização que é disposta no lado a montante na direção de carregamento da unidade de detecção magnética e gera, na trajetória de carregamento, um campo magnético de magnetização, sendo que a direção de campo magnético do qual é uma direção diferente da direção de campo magnético do campo magnético de polarização para, assim, magnetizar a substância magnética. na posição da detecção magnética pela unidade de detecção magnética, cada substância magnética é magnetizada em uma direção de magnetização diferente de acordo com uma força coerciva pelo campo magnético de magnetização e pelo campo magnético de polarização.
