These stripes often called zebra stripes, due to the alternating colors of the original magnetometer readings. When the first observations were made, it is directly related to two processes geomagnetic reversals and seafloor spreading.
Mid-Ocean Ridges
These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.
Magnetic stripes on the seafloor provide evidence for seafloor spreading because they show alternating bands of normal and reversed polarity along mid-ocean ridges. These stripes form as new oceanic crust is created at mid-ocean ridges, with the Earth's magnetic field aligning minerals in the crust in the direction of the prevailing polarity at the time of its formation. By collecting and analyzing samples from the ocean floor, scientists can observe these magnetic patterns and confirm the process of seafloor spreading over geologic time scales.

Magnetic stripes on the sea floor form as a result of the movement of tectonic plates. When magma rises to the surface at mid-ocean ridges and solidifies into new rock, it records the Earth's magnetic field at the time. This creates alternating stripes of normal and reversed polarity as the Earth's magnetic field has flipped multiple times throughout history.
Magnetic stripes can be seen as you move away from ocean ridges.
Mid-Ocean Ridges
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.
Magnetic stripes on the seafloor are alternating bands of magnetized rock that form parallel to mid-ocean ridges. These stripes are a result of Earth's magnetic field changing direction over time and getting preserved in the rocks as they cool and solidify. They provide evidence for seafloor spreading and plate tectonics.
parallel to and symmetric about ocean ridges

As you move away from an ocean ridge, the rocks get older.

Magnetic stripes on the ocean floor are formed as magma from the mantle rises at mid-ocean ridges and solidifies into rock. The Earth's magnetic field periodically reverses its polarity, causing magnetic minerals in the cooling rock to align with the prevailing magnetic field. These alternating magnetic orientations create stripes of normal and reversed polarity that are preserved in the oceanic crust as it spreads away from the ridges. By studying these magnetic stripes, scientists can reconstruct the history of the Earth's magnetic field reversals and the seafloor spreading process.
Ocean-floor rocks near mid-ocean ridges show a symmetrical pattern of magnetized stripes parallel to the ridge axis. These stripes result from periodic reversals in Earth's magnetic field and provide evidence of seafloor spreading. Sediments on the ocean floor also show younger ages near the ridges, supporting the idea of seafloor spreading.
