They appear to be similar in width because new crust formation is nearly equal on each side of the fault.

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.
Is Fayalite magnetic?
Yes, fayalite is magnetic, ithas a magnetic susceptibilty of approx 33 SI units, similar to prryhotite.
Is chalcopyrite and hematite and magnetite and pyrite magnetic?
some of our samples of pyrite are paramagnetic
What is the maximum magnetic variation on earth?
It will be 180 degrees in any position between the north magnetic pole and the geographical north pole and similar at the south pole
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.

What are 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.

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
What is the magnetic field of an electromagnet similar to?
a bar magnet...
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.
What are the magnetic sensors?
The simplest detection of a magnetic field is done by another magnet. Or by an apparatus such as a Fluxgate magnetometer or similar.
Why is the earth magnetic full detail?
The earth has a magnetic field which is similar to a magnetic bar tilted 11 degrees. This is caused because of the North and South pole.
Do magnets stick to silver?
No, silver is very similar to gold and is not magnetic. It does not turn magnetic on its own however in a magnetic field it magnetizes to a very little extent.
