6.
A magnetic compass points towards the north geographic pole of the Earth because
a)
all magnetic poles, north or south, point that way due to the spin of the Earth.
b)
there is a north magnetic pole near the north geographic pole.
c)
there is a south magnetic pole near the north geographic pole.

it points towards north and south
b)
it does not show the attraction between north and south
c)
it should point away from north
d)
all of the above
12.
Two students drew the magnetic field around a horseshoe magnet. Who was incorrect and why?

Student B because magnetic fields start on North and end on South
b)
Student B because magnetic field lines do not cross
c)
Student C because magnetic fields start on North and end on South
d)
Student C because magnetic field lines cross
13.
Which of the following is true if you were to break a magnet in two?
a)
The magnet would no longer be magnetic
b)
It would still be magnetic and just as strong
c)
It would still be magnetic and each piece would be half the strength
d)
there would be a North and a South magnet
14.

a)
increases regardless of whether they are repelling or attracting
b)
decreases regardless of whether they are repelling or attracting

increases but only if they are attracting

increases but only if they are repelling
