Imagine a Series of Mutually Repelling Ring Magnets Strung Along

Imagine a series of mutually repelling ring magnets strung along a nearly frictionless horizontal rigid rod. If one jostles a magnet near one end of the rod, it can cause a wave of disturbance to move down the rod through the other magnets. Will this be a (A) transverse or (B) longitudinal wave?

A) Transverse wave
B) Longitudinal wave
