These stripes represent polar inversions.
Strips of alternating polarities found in rocks in the ocean basins are the result of seafloor spreading. When new oceanic crust is formed at mid-ocean ridges, iron minerals in the magma align with Earth's magnetic field. Over time, as the crust moves away from the ridge, these magnetic minerals preserve the direction of the Earth's magnetic field at that time, creating alternating stripes of normal and reversed polarity on the seafloor.

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.
Magnetic fields are recorded by rocks in strips parallel to ridges on Earth's surface. This phenomenon is known as magnetic striping, and it provides evidence of seafloor spreading and the movement of tectonic plates over time.

Strips of alternating magnetic polarities found in ocean basin rocks provide evidence for seafloor spreading and plate tectonics. These magnetic anomalies are formed as magma cools and solidifies at mid-ocean ridges, recording the Earth's magnetic field at that time. The symmetrical pattern of these stripes on either side of the ridge indicates that new oceanic crust is created and pushes older crust away, supporting the theory of continental drift. This contributes to our understanding of the dynamic nature of the Earth's lithosphere.

They are arranged in a pattern with magnetic strips having reversed polarities.
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
Magnetic strips on the seafloor are caused in part by seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, it locks in the polarity of the Earth's magnetic field at the time, creating a recorded history of magnetic reversals. This process creates alternating stripes of normal and reversed polarity as the seafloor expands.
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.
Movement of the ocean crust
Some staplers have small magnetic strips to help keep staples in place, but in general, staplers are not inherently magnetic.
To effectively secure items using strong magnetic strips, ensure the strips are securely attached to a stable surface, such as a wall or cabinet. Place the items on the strips in a way that maximizes contact with the magnets for a strong hold. Additionally, consider using multiple strips for heavier items or extra security.
