Why do bands indicating magnetic reversals appear to be of similar width on both sides of a mid-ocean ridge?
They appear to be similar in width because new crust formation is nearly equal on each side of the fault.
What are Other than earth is also known to have magnetic pole reversals?
Other than Earth, Mars is also known to have experienced magnetic pole reversals in its history. Evidence from the planet's crust suggests that its magnetic field has reversed multiple times over millions of years, similar to Earth's magnetic field reversals.
Which body in our solar system has a magnet pole reversals?
The sun
What are the 6 pieces of evidence that prove the continents were once connected?
Fossil evidence of the same species found on different continents Similar rock formations and mountain ranges on different continents Matching coastlines and geological features on opposite sides of the Atlantic Ocean Similarity in plant and animal distributions on different continents Ancient climate data indicating past connections between continents The fit of the continental shelves when the landmasses are pieced together like a jigsaw puzzle.
Is chalcopyrite and hematite and magnetite and pyrite magnetic?
some of our samples of pyrite are paramagnetic

What are three characteristics of magnetic reversals?
In the past, the polarity of the Earth's magnetic field has reversed, many times over. This was discovered in samples of the rocks of the ocean floor at mid-ocean ridges, where matching patterns of magnetic polarity were discovered on each side of the mid ocean ridge. It is believed that the magnetic field is caused by electrical currents in the Earth's interior. [We know that the interior is too hot to sustain the magnetism of a bar magnet. As proved by the Curie's.] If these currents circulate parallel to the equator, then they would be pretty stable. but we know that the poles are moving. This may indicate that the path of electrical conduction is not a simple circle. We just have to wait. The earth's magnetic field is caused by the effect of the Earth's rotation on the liquid iron core. This field occasionally flips so that the direction that was magnetic north becomes magnetic south and what was magnetic south becomes magnetic north. This is called a magnetic reversal and these reversals can be detected in Earth's lava rocks which lock in the direction of the current field when they cool and solidify. Earth's magnetic field flips about once every 100 thousand years. The Sun goes through similar magnetic reversal cycles but on the Sun the reversals happen about once every 11 years.

What is the magnetic field of an electromagnet similar to?
The magnetic field of an electromagnet is similar to the magnetic field of a permanent magnet. Both exhibit magnetic properties and can attract or repel other magnetic materials. The strength of the magnetic field of an electromagnet can be controlled by adjusting the electrical current flowing through it.
Is eraser magnetic?
No, erasers are typically made of rubber or similar materials that do not have magnetic properties.
Is moon rock magnetic?
Moon rocks are very similar to earth rocks an they are not intrinsically magnetic.
The magnetic field of an electromagnet is similar to that of a magnet?
bar
Is spelter magnetic?
No, spelter is not magnetic. Spelter is simply a synonym for zinc and is similar to copper or brass as well.
What are the magnetic?
The simplest detection of a magnetic field is done by another magnet. Or by an apparatus such as a Fluxgate magnetometer or similar.
