A (opposites attract)
Since the tip of a compass point toward magnetic South, the tail of the compass must point towards the permanent magnets NORTH pole. C
Field lines point toward magnetic south. Thus, if you look directly at the south-pole of a bar magnet, the lines point AWAY from you.

4. The only ways to do this are to either break them both and see which ones pieces attract each other (BAD IDEA since now you broke your magnet) OR to place the end of one bar at the center of the other bar. If it attracts, the bar touching the center is the magnetized bar.

If you place a compass in front of a magnets North-Pole, it will point away from this pole. Since compass needles always point away from magnetic north and towards magnetic south, this confirms that the North-Pole really is magnetic South.
87. B (electron spins are the source of B-fields)

D (both the domain orientation and the domain boundaries may change when something is magnetized)
Heat the magnet up or drop the magnet repeatedly (“jostle” it).
94. D, non of the options were correct. The earth’s poles do reverse polarity, but it would take almost a million+ years for this to happen, according to current theories.
