Accelerating electric charges.
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
the answer is rotational force
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.

The Mid Ocean Ridge would have magnetic striping. As the seafloor expands, new oceanic crust is spread in either direction. As this process continues over many years, the magnetic poles may switch, altering the magnetism in the new crust. The poles will switch back and forth, producing the magnetic striping that is easily discernible when examining the Mid Ocean Ridge and surrounding seafloor.

Magma contains many materials which are magnetically affected. When this magma is ejected from the mantle and begins forming new crust, these materials align to the earth's magnetic field. The crust hardens, and the magnetic alignment is fixed (just as in normal magnets, made by using a similar process). The magnetic fields are 'visile' in strips of material, hence the term 'magnetic striping'. seafloor spreading
