Yes, the igneous rocks of the ocean floor exhibit a pattern of oppositely polarized magnetic strips. This demonstrates that the earth's magnetic field has reversed polarity (i.e. swapped north and south poles) several times in the past.

How do strips of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.

What kinds of magnetism did scientists finds while studying the ocean floor?
While studying the ocean floor, scientists found alternating bands of magnetism. Each band is magnetized with a polarity that is opposite the surrounding bands.
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
Linear magnetic patterns associated with mid-oceanic ridges are configured as what?
Linear, magnetic patterns associated with mid-ocean ridges are configured as normal and reversed magnetized strips roughly parallel to the ridge. A very long lived magma source located deep in the mantle is called a hot spot.
Why are magnetic strips on the sea floor are parallel to the mid ocean ridge?
Yes, but it can be influenced by volcanoes and earthquakes
Strips of alternating magnetic polarities found in rocks in the ocean basins?
provide evidence for sea-floor spreading
