what have you noticed when you pulled the magnet on top perpindicularly across the other?what does this tell you about the magnetic field around latch magnet?

Suppose we hold two bar magnets with opposite poles facing each other a certain distance away.
We let go and the magnets fly towards each other.
We observe that the magnets gain kinetic energy. Then work must have been done on their masses.
I am told that magnetic forces are always perpendicular to the velocity vector and hence cannot do work. But clearly here, the magnetic field has done work.
How can we reconcile the motion of the bar magnets with the statement about magnetic forces. I simply don't get it. If the magnetic field isn't whats providing the accelerative force, then what is?
