Hay muchas leyes que deben aprender, como la \u00abregla de la mano derecha\u00bb o la \u00abregla de la mano izquierda de Fleming\u00bb, pero no siempre es f\u00e1cil conseguir que los estudiantes perciban de forma intuitiva la existencia de un campo magn\u00e9tico que no podemos ver.<\/span><\/p>\n<p data-sourcepos=\"5:1-5:267\">Hoy quiero presentarles un experimento para observar el campo magn\u00e9tico que se forma alrededor de una corriente el\u00e9ctrica rectil\u00ednea utilizando un <strong>cable Pascal<\/strong>. <strong>El cable Pascal es un cable especial formado por 10 conductores conectados en paralelo en su interior. Aunque aparentemente circule una corriente de solo 1 A, se comporta como si por \u00e9l circularan 10 A.<\/strong> Gracias a ello, puede generar un campo magn\u00e9tico intenso incluso con una corriente relativamente peque\u00f1a, lo que permite observarlo con mucha mayor claridad.<\/p>\n<p data-sourcepos=\"5:1-5:267\">Miren este v\u00eddeo. Como se genera un campo magn\u00e9tico bastante intenso alrededor del cable, basta con colocar varias br\u00fajulas para observar f\u00e1cilmente c\u00f3mo se comporta el campo magn\u00e9tico.<\/p>\n<p><iframe loading=\"lazy\" title=\"\u30d1\u30b9\u30ab\u30eb\u96fb\u7dda\u3067\u78c1\u5834\u3092\u300c\u898b\u308b\u300d\uff01\u96fb\u6d41\u304c\u751f\u307f\u51fa\u3059\u898b\u3048\u306a\u3044\u529b\u306e\u6b63\u4f53\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/z6VKpd4Y8AU?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<p>Con un cable convencional es muy dif\u00edcil generar un campo magn\u00e9tico tan intenso, por lo que el experimento no funciona igual de bien.<\/p>\n<h3 data-sourcepos=\"11:1-11:10\">Materiales necesarios<\/h3>\n<ul data-sourcepos=\"15:1-24:0\">\n<li data-sourcepos=\"15:1-16:99\"><strong>Cable Pascal<\/strong>: para observar el campo magn\u00e9tico de una corriente rectil\u00ednea, lo ideal es utilizar uno de 10 m de longitud.<br \/>\nPara obtener m\u00e1s informaci\u00f3n sobre el cable Pascal, pueden consultar este art\u00edculo.

data-sourcepos=\"54:1-54:37\">A trav\u00e9s de este experimento, los estudiantes pueden profundizar en varios conceptos fundamentales de ciencias.<\/p>\n<p><strong>Relaci\u00f3n entre corriente el\u00e9ctrica y campo magn\u00e9tico<\/strong>: cuando circula una corriente el\u00e9ctrica, se genera un campo magn\u00e9tico a su alrededor.<\/p>\n<p><strong>Direcci\u00f3n del campo magn\u00e9tico<\/strong>: el campo magn\u00e9tico producido por una corriente rectil\u00ednea forma c\u00edrculos conc\u00e9ntricos alrededor del conductor, siguiendo la regla de la mano derecha con respecto a la direcci\u00f3n de la corriente.<\/p>\n<p><strong>Intensidad del campo magn\u00e9tico<\/strong>: cuanto mayor es la corriente el\u00e9ctrica, m\u00e1s intenso es el campo magn\u00e9tico generado. Ese es precisamente el efecto que aprovechamos con el cable Pascal.<\/p>\n<p><strong>L\u00edneas de campo magn\u00e9tico<\/strong>: los patrones que forman las limaduras de hierro permiten visualizar las l\u00edneas del campo magn\u00e9tico. Las l\u00edneas de campo salen del polo norte y entran en el polo sur, formando l\u00edneas cerradas sin interrupciones.<\/p>\n<p><strong>Campo magn\u00e9tico de una bobina<\/strong>: cuando hacemos circular una corriente por una bobina, se genera un campo magn\u00e9tico aproximadamente uniforme en su interior, mientras que en el exterior el campo adopta una forma similar a la de un im\u00e1n de barra.<\/p>\n<p>El cable Pascal permite realizar experimentos tan llamativos como este y resulta muy pr\u00e1ctico para hacer visible un campo magn\u00e9tico que normalmente no podemos ver. \u00a1Espero que puedan aprovecharlo en muchas situaciones diferentes!<\/p>\n<h3>Consultas y solicitudes<\/h3>\n<p>\u00a1Hagamos que las maravillas y la diversi\u00f3n de la ciencia est\u00e9n un poco m\u00e1s cerca!
