Which of these is true about a bar magnet?
(Points : 1)
Its north pole tends to point south.

Its poles can be separated into two isolated poles.

Its poles attract or repel because of their net electric charge.

It attracts unmagnetized iron objects by making them magnetically polarized.

I think the answer is D am I right???

@amistre64  what do you see in this problem?

amistre64 · Answer

i think there is more than one correct answer

fretje · Answer

it is D after all.  i was wrong

amistre64 · Answer

since opposites attract, a compasses north pole is attracted south

fretje · Answer

google says the north pole of a bar magnet by definition(or convention) points to the earth's north pole

fretje · Answer

and that the earth's north pole is by consequence of this convention, a magnetic south pole.  Also do they say that one does not need the earth to determine a bar magnets poles, one can use the right hand rule with an electromagnet.

fretje · Answer

but this is all boring physics, the physicists these days try to find anomalies and magnetic monopoles, so i would go for answer B, although i can still not prove that.
