Rocks lock in their magnetism when they cool.
Magnetic stripes can be seen as you move away from ocean ridges.
rocks get older as you move away from ocean ridges
provide evidence for sea-floor spreading
They are known as magnetic stripes and are formed as new sea floor is created at mid-ocean ridges. When molten rock solidifies, it preserves the direction of Earth's magnetic field at that time, creating a record of magnetic reversals in the oceanic crust. The alternating stripes of normal and reversed polarity provide evidence for seafloor spreading and plate tectonics.
The pattern of magnetic reversals along the sides of mid-ocean ridges resembles stripes that alternate in polarity, created as new oceanic crust is formed at mid-ocean ridges and records the Earth's changing magnetic field. These magnetic stripes provide evidence for seafloor spreading and plate tectonics.

Because of the stripes at the sea floor which are magnetic minerals
Magnetic reversals provide strong evidence of the Earth's shifting magnetic field over geological time scales. These reversals, recorded in the ocean floor's basaltic rocks, support the theory of plate tectonics by demonstrating seafloor spreading and continental drift. The patterns of magnetic striping on either side of mid-ocean ridges show symmetrical changes in polarity, reinforcing the idea of new crust being formed and pushed away from these divergent boundaries. This evidence is crucial for understanding the dynamic processes that shape our planet.
Magnetic reversals provide strong evidence for the process of seafloor spreading at the bottom of the ocean. As magma rises and solidifies at mid-ocean ridges, it records the Earth's magnetic field direction, which periodically reverses. This creates a pattern of magnetic stripes on either side of the ridge, demonstrating how new oceanic crust is formed and pushed away from the ridge over time. These patterns serve as key evidence for the theory of plate tectonics.

They technically don't. They do provide evidence for it, however, in that they occur in pairs on either side of a rift, providing strong evidence that the rocks on either side were deposited at the same time and that the rifts are spreading.
