11. How are electrical charges and magnetic poles similar? More than one might apply
A. Unlike attract and the same repel
B. Both are plus and minus
C. Magnetic poles attract electrons
D. You can represent their effect using fields
18. A bar magnet has two poles — a north pole and a south pole. If the bar was cut in half
A. each half would be either north or south
B. each half would have its own north pole or south pole
C. each half couldn’t be attracted to the other half
D. each half would lose its magnetism
19. The total resistance in a circuit containing resistors connected in series is given by
A. The sum of the individual resistance
B. The sum of the currents
C. The sum of the inverses of the individual resistances
D. The sum of the voltage
20. You are looking straight down on a magnetic compass that is lying flat on a table. A wire is stretched horizontally under the table, parallel to and a short distance below the compass needle. The wire is connected to a battery so that a current flows through the wire. This current causes the north pole of the compass needle to deflect to the left. If the wire is lowered farther from the compass, the angle of deflection should…
A. Increase
B. Decrease
C. Remain unchanged
D. Flip wildly around
