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.

WHY do similar sides attract on a magnet?

SIMILAR repel, opposites attract. And they are because of that because of the magnetic fields.


The gravity lock of the Moon to the Earth is similar to the action of a master key?

An XRAY.


Are magnetic forces bad for computers?

Magnetic forces are not necessarily bad for computers, as mechanical hard disks use them to store information. However, you shouldn't place any magnetic objects near them as it will ruin your data that's store on those kinds of disks.

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.

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.
