The plate tectonics based theory ha a three pronged aproach; both the zebra-like magnetic striping and the construction of the mid-ocean ridge system, the seafloor spreading hypothesis (SFS) quickly gained converts and represented another major advance in the development of the plate-tectonics theory. Furthermore, the oceanic crust now came to be appreciated as a natural "tape recording" of the history of the geomagnetic field reversals (GMFR) of the Earth's magnetic field. Nowadays, extensive studies are dedicated to the calibration of the normal-reversal patterns in the oceanic crust on one hand and known timescales derived from the dating of basalt layers in sedimentary sequences (magnetostratigraphy) on the other, to arrive at estimates of past spreading rates and plate reconstructions.
Electrical into magnetic, and then magnetic into mechanical.
nothing will happen dumbazz because it isnt magnetic
short answer: bye-bye data long answer: the magnetic forces in the magnet scramble the magnetic domains on the magnetic card, thus killing the data on the card
The compass will align itself with the magnetic field generated by the current flow through the wires.
The magnetic forcefield of the earth protects us from harmful radiation from the sun. No magnetic force - we'd fry.
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
The pattern of magnetic striping on one side of the ridge was a mirror image of the striping on the other side of the ridge, indicating that the plates were moving equally in opposite directions, giving a plausible explanation for continental drift theory. Before this discovery, no evidence of a mechanism for plate tectonics existed. It was obvious after this discovery, that new crust was being created at the ridges.
Harry Hess proposed an explanation that tied together data on the age of ocean rocks, sediment thickness, and magnetic striping.
