En realidad, las cosas no son tan simples. Basta con a\u00f1adir una sola &#8220;bobina&#8221; al circuito para que la corriente deje de obedecer d\u00f3cilmente y, como si alguien pisara el freno, se vaya elevando poco a poco. Esta vez, utilizamos un sensor llamado EasySense (de DataHarvest), adquirido a trav\u00e9s de Narika, para capturar en vivo ese fen\u00f3meno tan curioso conocido como &#8220;autoinducci\u00f3n&#8221;.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-37308 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396.jpg\" alt=\"\" width=\"488\" height=\"366\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396-768x576.jpg 768w\" sizes=\"auto, (max-width: 488px) 100vw, 488px\" \/><br \/>\nPrimero, echa un vistazo a este video:<br \/>\n<iframe loading=\"lazy\" title=\"\u30bb\u30f3\u30b5\u30fc\u3067\u898b\u308b\u81ea\u5df1\u8a98\u5c0e\u306e\u5b9f\u9a13\u3010EasySense DataHarvest\u3011\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/28xLrtacdMw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h3>\u00bfQu\u00e9 es la autoinducci\u00f3n? La &#8220;duda&#8221; que muestra la bobina<\/h3>\n<p>Cuando intentamos hacer pasar corriente por una bobina, esta parece resistirse al cambio: genera una fuerza electromotriz inducida en sentido contrario a la variaci\u00f3n de la corriente. A esto se le llama autoinducci\u00f3n. Al igual que las oscilaciones el\u00e9ctricas que presentamos anteriormente, este fen\u00f3meno ocurre en fracciones de segundo, lo que hace imposible seguirlo a simple vista o con un amper\u00edmetro convencional. Por eso, aqu\u00ed entra en juego un sensor capaz de capturar datos a alta velocidad.<\/p>\n<h3>Sin perder ni 0,0005 segundos: la configuraci\u00f3n del EasySense<\/h3>\n<p>En esta ocasi\u00f3n, configuramos el EasySense con un tiempo de medici\u00f3n de 200 milisegundos y un intervalo de muestreo de 2000 veces por segundo. Dicho de otro modo: el sensor es capaz de registrar nada menos que 2000 datos por segundo. Con esa resoluci\u00f3n tan fina, lo que al ojo humano parece un simple parpadeo \u2014el &#8220;arranque&#8221; de la corriente\u2014 queda reproducido en la gr\u00e1fica como una curva suave y perfectamente definida.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-36879 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/382fbd03e816e50b0d791dee4d7745f8.jpg\" alt=\"\" width=\"336\" height=\"284\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/382fbd03e816e50b0d791dee4d7745f8.jpg 724w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/382fbd03e816e50b0d791dee4d7745f8-300x254.jpg 300w\" sizes=\"auto, (max-width: 336px) 100vw, 336px\" \/><\/p>\n<h3>\u00a1No solo el volt\u00edmetro!

El volt\u00edmetro va en paralelo, el amper\u00edmetro en serie. Es una regla b\u00e1sica que ya se aprende en la escuela, pero que en la pr\u00e1ctica siempre hace que uno se detenga a pensar: &#8220;espera&#8230; \u00bfcu\u00e1l era cu\u00e1l?&#8221;. Un cl\u00e1sico tropiezo que casi todos hemos tenido.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-37308 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396.jpg\" alt=\"\" width=\"488\" height=\"366\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4396-768x576.jpg 768w\" sizes=\"auto, (max-width: 488px) 100vw, 488px\" \/><\/p>\n<h3>Lo que revelan los datos: el secreto de la &#8220;resistencia&#8221; de la bobina<\/h3>\n<p>Y ahora s\u00ed, los resultados. En la gr\u00e1fica, la l\u00ednea azul representa el circuito sin bobina, y la l\u00ednea roja, el circuito con bobina. En el circuito sin bobina, la corriente alcanza su valor m\u00e1ximo casi al instante de cerrar el interruptor. En cambio, en el circuito con bobina, la corriente no sube de golpe: se registra claramente c\u00f3mo va aumentando de forma gradual, con una lentitud que contrasta de manera notable.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-37306 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4399.jpg\" alt=\"\" width=\"800\" height=\"369\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4399.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4399-300x138.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/12\/IMG_4399-768x354.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><br \/>\nEn t\u00e9rminos de tiempo real, todo ocurre en un abrir y cerrar de ojos. Y sin embargo, que ese instante quede plasmado como una curva tan elegante me llen\u00f3 de asombro. Hay algo especial en ese momento en que un fen\u00f3meno que solo exist\u00eda como teor\u00eda en los libros de texto aparece frente a tus ojos convertido en una gr\u00e1fica, en una &#8220;prueba&#8221; real. Por mucho que uno lo experimente, siempre logra que el coraz\u00f3n se acelere un poco.<\/p>\n<h3>\u00bfPor qu\u00e9 la bobina hace &#8220;dudar&#8221; a la corriente?<\/h3>\n<p>Detr\u00e1s de este fen\u00f3meno est\u00e1 la Ley de Lenz. Cuando la corriente que atraviesa una bobina intenta cambiar, la bobina genera por s\u00ed misma una fuerza electromotriz en sentido contrario para contrarrestar ese cambio. Es como si el mundo el\u00e9ctrico tuviera su propia versi\u00f3n de la &#8220;inercia&#8221;: una tendencia a resistirse a los cambios bruscos.<br \/>\nY esto no es algo que solo ocurre en un laboratorio. Los transformadores, los motores, las cocinas de inducci\u00f3n, la carga inal\u00e1mbrica de los tel\u00e9fonos inteligentes&#8230; La autoinducci\u00f3n y la inducci\u00f3n electromagn\u00e9tica son los h\u00e9roes an\u00f3nimos que sostienen la vida moderna. Entender ese peque\u00f1o &#8220;titubeo&#8221; que nos muestra una bobina puede hacer que la electricidad, esa presencia invisible que nos rodea, se sienta de repente mucho m\u00e1s cercana.<\/p>\n<h3>Consultas y solicitudes<\/h3>\n<p>\u00a1Acercando la ciencia a todos de forma divertida y sencilla!
