F\u00edsica i Qu\u00edmica 2n d\u2019ESO<\/b><\/p>\n

Aquesta \u00faltima setmana hem fet una pr\u00e0ctica amb tot 2n d\u2019ESO en qu\u00e8 hem treballat les forces a dist\u00e0ncia i, entre elles, la for\u00e7a magn\u00e8tica. Per explicar com actuen les forces a dist\u00e0ncia \u00e9s \u00fatil la idea de camp de forces.<\/span><\/p>\n

El camp magn\u00e8tic d\u2019un imant, el camp el\u00e8ctric d\u2019un cos carregat o el camp gravitatori de la terra s\u00f3n zones d\u2019influ\u00e8ncia al voltant d\u2019aquests cossos, on uns poden exercir forces sobre d\u2019altres. Els camps magn\u00e8tics creats pels imants (com tots els camps) s\u00f3n invisibles, per\u00f2 l\u2019experiment que vam fer ens va permetre \u201cvisualitzar-los\u201d.<\/span><\/p>\n

Amb un imant, un full de paper i llimadures de ferro vam poder visualitzar la forma i direcci\u00f3 de les l\u00ednies del camp magn\u00e8tic generat per l\u2019imant (tamb\u00e9 anomenat espectre magn\u00e8tic), ja que les llimadures de ferro es van orientar seguint aquestes l\u00ednies de for\u00e7a.<\/span><\/p>\n
