contribuci\u00f3n de Maxwell fue corregir en parte y reunir en un solo tratado las investigaciones de otros f\u00edsicos, entre ellos, un franc\u00e9s que cincuenta a\u00f1os antes hab\u00eda explicado c\u00f3mo una corriente el\u00e9ctrica produce un campo magn\u00e9tico, y con cuyo apellido ser\u00eda bautizada la unidad de intensidad de esta corriente. \u00bfDe qui\u00e9n hablamos?<\/li>\n\n\n\n<li>Hay una propiedad el\u00e9ctrica intr\u00ednseca de ciertas part\u00edculas subat\u00f3micas que puede ser positiva o negativa, y que se manifiesta en el campo electromagn\u00e9tico como fuerza de atracci\u00f3n entre dos part\u00edculas que tienen propiedades distintas o de repulsi\u00f3n si tienen la misma. \u00bfC\u00f3mo se llama esa propiedad?<\/li>\n\n\n\n<li>Uno de los pilares de la s\u00edntesis te\u00f3rica que hizo Maxwell es la ley que dice que el flujo de ciertos campos a trav\u00e9s de una superficie cerrada es proporcional a la magnitud de las fuentes de ese campo que est\u00e1n en el interior de esa misma superficie. Se la conoce como \u201cley de \u2026..\u201d, porque fue formulada por un c\u00e9lebre matem\u00e1tico alem\u00e1n, de nombre Carl Friedrich. \u00bfY de apellido?<\/li>\n\n\n\n<li>Otro descubrimiento central que abon\u00f3 las cuatro \u2026\u2026\u2026. de Maxwell fue la inducci\u00f3n electromagn\u00e9tica, debido a un famoso cient\u00edfico brit\u00e1nico. Se llamaba Michael, \u00bfcu\u00e1l era su apellido?<\/li>\n\n\n\n<li>El matem\u00e1tico franc\u00e9s que describi\u00f3 la ley de atracci\u00f3n que genera esa propiedad el\u00e9ctrica de la pregunta 2, tambi\u00e9n aport\u00f3 su apellido para denominar a la unidad que se usa para medirla. \u00bfDe qui\u00e9n hablamos?<\/li>\n\n\n\n<li>El comportamiento electrost\u00e1tico de cualquier material es descripto por tres campos el\u00e9ctricos macrosc\u00f3picos: uno es el campo el\u00e9ctrico; el otro, el desplazamiento el\u00e9ctrico; \u00bfy el tercero?<\/li>\n\n\n\n<li>A\u00f1os antes de dar forma definitiva a su tratado, Maxwell hab\u00eda demostrado que el campo el\u00e9ctrico y el campo magn\u00e9tico se desplazan a trav\u00e9s del espacio a la velocidad de la luz, en forma\u2026 \u00bfde qu\u00e9?<\/li>\n\n\n\n<li>Dec\u00edamos que las formulaciones de Maxwell abrieron el camino de la f\u00edsica moderna. \u00bfC\u00f3mo llamamos hoy a la part\u00edcula elemental responsable de las manifestaciones cu\u00e1nticas asociadas a la propagaci\u00f3n del campo electromagn\u00e9tico?<\/li>\n\n\n\n<li>Las cuatro \u2026\u2026\u2026. de Maxwell explican cualquier fen\u00f3meno electrom\u00e1gnetico junto a la \u2026\u2026 de Lorentz, que describe c\u00f3mo act\u00faa un campo electromagn\u00e9tico sobre cargas en movimiento. \u00bfLa qu\u00e9 de Lorentz?<\/li>\n\n\n\n<li>En 1922, durante una entrevista en Cambridge, a un c\u00e9lebre f\u00edsico le dijeron que \u00e9l hab\u00eda hecho grandes cosas porque se subi\u00f3 a los hombros de Newton, y contest\u00f3: \u201cNo, no es as\u00ed, me apoyo en los hombros de Maxwell\u201d. \u00bfQui\u00e9n dijo esa frase?<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"Exactamente hace 150 a\u00f1os, el 24 de abril de 1873, sal\u00eda en la revista Nature una rese\u00f1a sobre el \u201cTratado sobre Electricidad y Magnetismo\u201d, de James Clerk Maxwell, publicado poco antes por Clarendon Press Series, Macmillan &amp; Co., donde el f\u00edsico escoc\u00e9s expuso por primera vez sus famosas \u201cigualdades entre expresiones matem\u00e1ticas\u201d, que unificaron los&#8230; <a class=\"view-article\" href=\"https:\/\/exactas.uba.ar\/web\/palabras\/exactamente-2\/\">LEER +<\/a>","protected":false},"author":1,"featured_media":109,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-54","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ciencia"],"acf":[],"_links":{"self":[{"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/posts\/54","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/comments?post=54"}],"version-history":[{"count":7,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/posts\/54\/revisions"}],"predecessor-version":[{"id":99,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/posts\/54\/revisions\/99"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/media\/109"}],"wp:attachment":[{"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/media?parent=54"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/categories?post=54"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/exactas.uba.ar\/web\/palabras\/wp-json\/wp\/v2\/tags?post=54"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
