Abstract
Un dispositivo magnetico conmutable incluye un primer iman (10) y un segundo iman (11) ambos de los cuales son esencialmente cilindricos. Los imanes (10, 11) estan alojados en un alojamiento hecho a partir de piezas polares (12, 13) las piezas polares (12, 13) son ferromagneticas. El iman inferior (10) esta montado en forma fija en el alojamiento, mientras que el iman superior (11) puede girar dentro del alojamiento. El iman superior (11) tiene formadas muescas o ranuras (14, 15) a lo largo de sus paredes laterales verticales. Estas muescas o ranuras (14, 15) reciben los brazos que cuelgan hacia abajo (16, 17) de la barra (18). La barra (18) es recibida dentro de una ranura (19) formada sobre el reborde (20) el reborde (20) esta conectado a una barra corta (21) que, a su vez, esta conectada en forma fija a una manija o palanca (22). Mediante esto, la rotacion de la manija o palanca (22) causa la rotacion del segundo iman (11). Cuando el iman superior (11) esta colocado de forma tal que su polo norte quede substancialmente por encima del polo sur del iman inferior (10) y el polo sur del iman superior (11) quede substancialmente por encima del polo norte del iman inferior (10), el primer y segundo imanes actuan como una derivacion magnetica activa, interna, y como un resultado la intensidad de campo magnetico, externo, del dispositivo, es bastante baja. La rotacion del iman superior (11) 180¦ alrededor de su eje de rotacion, pone a los imanes en alineacion, de manera tal que los polos norte y sur respectivos, del iman superior (11) queden substancialmente por encima de los polos norte y sur, respectivos, del iman inferior (10). En esta alineacion, el campo magnetico externo del dispositivo es bastante fuerte y el dispositivo puede fijarse a superficies u objetos. La figura mas representativa de la invencion es la numero 2.
