Answer 45 N attractive Back to Jeopardy Magnetism A device that uses induction to convert mechanical energy to electrical energy Answer Generator Back to Jeopardy Magnetism Converts electrical energy to mechanical energy. Instead of a current being generated by a rotating loop in a magnetic field, a current is supplied to the loop by an emf source and the magnetic force on the current loop causes it to rotate Answer Motor Back to Jeopardy Magnetism Like magnetic poles ______ And opposite magnetic poles _______ Answer Repel Attract Back to Jeopardy Magnetism The minimum number of poles for magnet is . . . Answer Two Back to Jeopardy Magnetism A very strong magnet attracts both poles of a weak magnet. Why? Answer It realigns the domains of the weaker magnet Back to Jeopardy Famous Dead Guys Supported idea of 2 types of charges. Invented the Lightning Rod Answer Ben Franklin Back to Jeopardy Famous Dead Guys His oil drop experiment proved 1.60 x 10-19 C the charge of the electron. He applied Coulomb’s Law to measure the charge Answer Robert Millikan Back to Jeopardy Famous Dead Guys Performed the Gold Foil experiment which established the planetary model of an atom that has electrons orbiting around a heavy, positively charged nucleus, which disproved the “plum pudding” model. He utilized alpha particles and gold foil.
