```It all depends on which way around the magnets are. Each magnet has
2 ends, a north pole and a south pole, opposite poles attract each
other and like poles push away from each other.

So in this arrangement of 3 bar magnets  N-S   S-N    S-N the middle
one will move to the right.

So in this arrangement of 3 bar magnets N  S   S   the middle one

S  N   N
will move left.

However, in this situation N-S   S-N   N-S the middle one is pushed
away by both sides and will move forward or back

and here S-N   S-N   S-N the middle one will move to the side of
the magnet with the stronger pole. The nearer the pole the stronger
it is.

Even though magnets might look the same they will have different
strengths as indivual magnets lose their magnetism at different
rates depending on how they are treated.
