Two bar magnets are labeled a and b. the ends of each magnet are numbered 1 or 2, but the poles are not labeled. when a1 is brought near b1, the bars repel. which conclusion is best supported by the data? a) a1 is the north pole of a magnet, and b1 is the south pole of a magnet. b) a1 is the north pole of a magnet, and b1 is the north pole of a magnet. c) a1 and b1 are opposite poles, but there is not enough information to tell which ones. d) a1 and b1 are like poles, but there is not enough information to tell whether they are north poles or south poles.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
