If moving charges are positive, then current flows in the direction of the charges. 50% 50% A. True B. False True False
If moving charges are negative, then current flows in the direction of the charges. 50% 50% A. True B. False True False
Two wired, exact in every way, except that one is twice as long as the other, are placed in a magnetic field in the same orientation. As current flows through each wire, the force on the wire due to the magnetic field is the same for both wires. 50% 50% A. True B. False True False
