Do the earths magnetics at the equator cause river flow directions?
No. Quite a few factors affect the direction a river takes. First of all, water runs downhill due to gravity. It may flow northward or southward, to the east, or to the west, but always downhill. Where water is forced to move uphill, for short distances over rocks or small inclines, the force of the flowing water must be sufficient to overcome the gravitational pull downward or the water will stop flowing; alternately the water could fill and then overflow a basin. The exact course a river or stream takes depends on a combination of many factors. Magnetics at the equator do not play a part in any significantly measurable manner.
