Problem 23. A positive test charge qtest is placed at
rest equidistance between the north and south poles of two
identical bar magnets (see figure). What is the net force on the
charge from the two magnetic poles? Suppose the magnetic strength
of one of the two bar magnets is doubled, what is the net force on
the charge from the two magnetic poles now?
