FEM UN MOTOR DE CONTÍNUA

Als alumnes de segon avui se'ls ha plantejat un repte: 
"Amb els següents materials:
-2 xinxetes
-2 clips
-1 imant
-Una base de fusta
-Fil de coure
i una font d'alimentació
Realitzeu un motor de contínua...." 
Com ha anat? Doncs bé, crits d'alegria quan ha començat a girar sola la bobina de coure i contents d'haver-ho dissenyat tot ells!

  1. The sportsbook then set its sights on U.S. enlargement, and made some pretty fast features. At the time of writing, the operator is reside in Colorado, Illinois, Indiana, Iowa, Michigan, New Jersey, New York, Pennsylvania, Virginia, and West Virginia. You’ll find almost as many props right here as the other prime 1xbet korea sportsbooks listed above. All the tabs you’ll need to navigate the app are positioned on the bottom of the display, front and center at all times — Home, A-Z Menu, Betslip, My Bets, and Promotions.
