Cada d\u00eda es un nuevo experimento.<\/strong><\/span><\/p>\n<p>Al apagar un interruptor, uno podr\u00eda pensar que la corriente desaparece al instante. Sin embargo, en la pr\u00e1ctica no ocurre as\u00ed. La bobina se resiste a dejar de conducir la corriente y provoca una intensa oscilaci\u00f3n del voltaje, como si insistiera en que la corriente siga fluyendo. En este art\u00edculo veremos un experimento de demostraci\u00f3n en el que utilizamos un sensor para hacer visible esa &#8220;terquedad&#8221; de la bobina.<\/p>\n<h3>Preparaci\u00f3n del circuito experimental<\/h3>\n<p>Utilizamos un sensor para observar las oscilaciones el\u00e9ctricas. Primero montamos un circuito como el que se muestra a continuaci\u00f3n y hacemos circular corriente por la bobina. Despu\u00e9s, apagamos el interruptor de forma repentina y medimos el voltaje de la bobina con un sensor de voltaje. En este experimento se utiliz\u00f3 un EasySense V-Hub.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-37589\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_1816.jpg\" alt=\"\" width=\"420\" height=\"315\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_1816.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_1816-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_1816-768x576.jpg 768w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><\/p>\n<p style=\"text-align: left;\">La configuraci\u00f3n del sensor es la siguiente.

Es como si dijera: &#8220;\u00a1No te detengas tan deprisa!&#8221;. Esta propiedad se debe a la <b>inductancia<\/b> de la bobina. Cuando una bobina se combina con un condensador forma un circuito LC, capaz de producir oscilaciones el\u00e9ctricas. Este mismo principio permite, por ejemplo, que una radio seleccione y reciba una frecuencia espec\u00edfica.<\/p>\n<h3>Al colocar una pieza de hierro sobre la bobina&#8230; cambia el per\u00edodo<\/h3>\n<p>Si colocamos un trozo de hierro sobre la bobina y <b>modificamos su autoinductancia<\/b>, el per\u00edodo de la oscilaci\u00f3n tambi\u00e9n cambia, como se observa a continuaci\u00f3n. \u00bfNotas que la separaci\u00f3n entre las ondas es diferente? Cuanto mayor es la inductancia, m\u00e1s lentamente oscila el circuito el\u00e9ctrico. La idea es muy parecida a la de un p\u00e9ndulo pesado, que tarda m\u00e1s tiempo en completar una oscilaci\u00f3n. En el mundo de la electricidad tambi\u00e9n existe algo equivalente a la &#8220;masa&#8221;. Pensar en ello de esta manera hace que la f\u00edsica resulte a\u00fan m\u00e1s fascinante.<\/p>\n<div class=\"g-ytsubscribe\" data-channelid=\"UCBoF1yPvFnXnSJ_Xe5AmXcw\" data-layout=\"full\" data-count=\"default\">La autoinducci\u00f3n da la impresi\u00f3n de que la bobina tiene voluntad propia. Gracias a los sensores, podemos transformar esas oscilaciones invisibles de la electricidad en una forma que s\u00ed podemos observar. Sin duda, es uno de esos experimentos que merece la pena mostrar a los estudiantes.<\/div>\n<h3>Consultas y colaboraciones<\/h3>\n<p>\u00a1Acerca la ciencia a tu vida cotidiana!
