What force creates a magnetic force?
Typically, an electric current creates a magnetic force. Also, magnetic domains aligned correctly and properly can cause a magnetic force.
How does magnetic reversals found in the sea floor rocks cause continental drift?
Magnetic reversals found in the sea floor do not cause continental drift. It does however provide evidence that sea floor spreading occurs (and hence is evidence for the theory of plate tectonics). This is because the iron rich minerals in basaltic rocks (such as magnetite) are at high temperatures when they are first intruded into the crust and at these high temperatures they record the orientation of Earth's magnetic field. As they cool, this record of the orientation of the magnetic field is "locked" in place. The Earth's magnetic field is known to "reverse polarity" - the north and south magnetic poles switch over time and so the orientation of the magnetic field in newly cooled rocks will change to match this. Geophysicists had recognised that there were alternating bands of rocks with these reversed orientations of the magnetic field. These bands ran parallel to the Mid-Ocean-Ridges. In the 1960s after significant magnetic survey work was undertaken it was realised that the alternating bands on one side of the oceanic ridge were a mirror image to the bands on the other side. So why is this evidence for sea floor spreading / plate tectonics? Well it was realised that if the newly intruded rock was to move away from the Mid-Ocean-Ridge (M-O-R) and be replaced with new younger rock, this rock would continue to record the orientation of the Earth's magnetic field as and when reversals occurred. As such this would lead to the stripes of alternating magnetic orientation that are symmetrical about the M-O-R. As such movement of the plates away from a M-O-R and the reversals of Earth's magnetic field best explained the presence of these bands and so confirmed the idea that sea floor spreading was occurring.

Could the earth's magnetic poles be the cause of continental drift?
No, the Earth's magnetic poles are not responsible for continental drift. Continental drift is primarily driven by the movement of tectonic plates in the Earth's lithosphere. The Earth's magnetic field does play a role in plate tectonics through magnetic stripes on the ocean floor, but it is not the primary cause of continental drift.
Is all steel magnetic?
No, not all types of steel are magnetic. Stainless steel, for example, contains a high amount of chromium and is generally not magnetic. On the other hand, carbon steel, which typically has a higher iron content, is usually magnetic.
What are tiny regions inside all objects that cause an object to be magnetic when they line up?
Magnetic domains are tiny regions within materials where atoms align their magnetic fields in the same direction. When these domains line up, the material exhibits magnetic properties.
Why does friction cause a magnetic force?
Friction does not directly cause a magnetic force. Friction is a force that resists motion between two surfaces in contact. Magnetic forces, on the other hand, arise from the interaction between moving charged particles and magnetic fields. These forces are independent of friction and are a fundamental property of magnetic materials.
Which structures of the dermis give rise to friction edges or fingerprints?
Friction ridges or fingerprints are formed by the patterns of raised skin ridges in the papillary layer of the dermis. These ridges are made up of dermal papillae, which project into the epidermis and create unique patterns that form fingerprints.
What causes an electromagnet to cause motion?
A magnet, permanent or electro-, will induce an opposite magnetic field in a ferromagnetic material. These two fields will attract, and if either of the members is free to move it will do so. Hans Oersted, a Dane, in 1820 noticed that an electrical current caused a nearby magnetic needle to move.
What is the magnetic character for iron?
the answer is the iron of magnetic field so that it can cause magnetic field... iron.
What did scientists think happened to cause the magnetic patterns they found?
Scientists believe the magnetic patterns observed in geological formations are primarily due to the process of seafloor spreading and the Earth's magnetic field reversals. As magma rises at mid-ocean ridges and solidifies, it records the Earth's magnetic orientation at that time. When the magnetic field reverses, new rock layers form with the opposite magnetic orientation, creating a symmetrical pattern on either side of the ridge. This evidence supports the theory of plate tectonics and helps explain the movement of Earth's lithospheric plates.
Do divergent boundaries cause island arcing?
No. Divergent boundaries cause mid ocean ridges (MORs) to form.
What topographic features do moving plates cause?
Made ocean ridges & mountains
What cause electromagnet cause motion?
because of the magnetic field.
Is scoria magnetic?
it is not magnetic because, i have many of them.
Does the inner core and outer core spin separately and is this why magnetic and true north are different?
I don't think that they spin in oposite directions if that's what you mean. Magnetic north and true north are completely unrelated. True north is a geographical location that lies on earth's axis. Magnetic north is just what they call it. At somepoint they must have noticed that earth's magnetic poles seemed to line up with north and south so that's what they named magnetic poles since they could be used for navigation. The core's spinning does cause the magnetic poles to move though.
What can cause realignment of magnetic domains in a material?
A magnet.
A wire cannot cause a magnetic field if what?
A wire cannot cause a magnetic field if there is no current flowing through it. Magnetic fields are generated by the flow of electric current in a conductor.
