problema esercizio esercizio... AIUTO GUN

ciao ragazzi...volevo chiedere un aiuto a qualcuno...purtroppo non mi viene un esercizio...magari e' anche una cavolata pero non riesco a capire una paio di cose

http://www.mi.infn.it/~colo/XXX/Inf...tembre_2007.pdf

(ESERCIZIO n 5) perche' la fem indotta E = -2at...da cosa deriva quel 2???...non dal numero di spire visto che ne ho solo una..giusto??

(ESERCIZIO n 4) non mi viene il valore della forza...noi l'abbiamo calcolato con l'angolo = 27 gradi.. la distanza 123 x 10 ^ -22.....e la forza finale 4 x 10 - 7....


fatemi sapere.....chiedo una mano a gun...grazie ciao
