Abstract

La presente invención se refiere a en un aparato de rayos catódicos que tiene una pantalla para ver, un elemento para producir un haz de partículas cargadas dirigido hacia dicha pantalla desde la parte posterior de la misma, y alineado con un eje central, pero que puede ser magnéticamente desviado de dicho eje, y una bobina de desviación que tiene un componente magnético a partir de segmentos de alambre axialmente alineados, y un componente magnético a partir de segmentos de alambre circunferencialmente alineados en relación con dicho eje, dando lugar a un campo magnético distribuído por red en frente de dicha bobina, un aparato para reducir dicha radiación magnética distribuída por red en frente de dicha pantalla, el cual comprende: un elemento de interruptor magnético dispuesto entre dicha bobina y dicha pantalla, comprendiendo dicho elemento de interruptor magnético un material magnéticamente permeable que tiene su configuración y su posición en relación con dicha bobina, dicho campo magnético distribuído por red en frente de dicha bobina.
