Suppose a magnetic reversal occured today. How would new rocks at mid-ocean ridges differ from rocks from form?

How would the new rocks differ from the rocks that formed last yearSuppose a magnetic reversal occured today. How would new rocks at mid-ocean ridges differ from rocks from form?
The rocks that are currently forming are ';normally'; magnetized, i.e., indicate that they formed during a period in which the Earth had normal polarity of its N and S magnetic poles. If a mag. reversal were to take place today, the new rocks forming at the MORs would have ';reverse'; magnetization, basically orienting themselves with the new configuration of the magnetic poles.Suppose a magnetic reversal occured today.

The iron particles after the reversal would be facing a different way than the previous ones. It is microscopic, so nobody can see it without studying it in a lab or something. :)
their only difference would in their magnetic signature it would be 180 degrees out of phase with the previous magnetic field
the north pole would be the south pole
