Abstract
Un desprendedor magnético tiene un imán central y un imán en forma de anillo. El imán central tiene un cuerpo con una superficie superior y una inferior, y produce un primer campo magnético. El imán en forma de anillo define una cavidad. El imán en forma de anillo tiene un cuerpo con una superficie superior y una inferior y produce un segundo campo magnético. El imán en forma de anillo está alineado de manera axial con el imán central de tal manera que el primer campo magnético se opone al segundo campo magnético a lo largo de los cuerpos y lo aumenta dentro de la cavidad. La superficie superior del imán central está separada de la superficie inferior del imán en forma de anillo por una distancia predeterminada produciendo así un campo magnético resultante que tiene una primera fuerza de campo resultante en una posicion específica mayor que una segunda fuerza de campo resultante producida en la misma posicion cuando la superficie superior del imán central empalma con la superficie inferior del imán en forma de anillo.
