What else can I help you with?
When the Earth's polarity is reversed is the Coriolis effect also reversed?
No. The reversal of polarity is a reversal of Earth's magnetic poles. The Corilolis effect is a direct consequence of Earth's rotation and is not affected by the magnetic field.
Does the earths magnetic field has periodically reversed direction?
Yes, the Earth's magnetic field has periodically reversed its direction throughout history. These reversals are known as geomagnetic reversals and have occurred many times over the past few million years.
Do iron rich rocks have reversed polarity or no magnetic proparty?
Iron-rich rocks can exhibit both normal and reversed magnetic polarity. When these rocks cool and solidify, the minerals containing iron align with the Earth's magnetic field. Over time, the Earth's magnetic field can reverse, causing the mineral alignment to also reverse, resulting in rocks with reversed polarity.
Bands of rock the seafloor showing alternating magnetic orientation indicate earth's magnetic field has?
reversed itself in the past. hth :)
What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
How is the force affected when the current is reversed in a magnetic field?
The magnetic field would reverse.
How many times has the earth's magnetic field reversed itself in the past?
The Earth's magnetic field has reversed hundreds of times in the past, with the most recent reversal occurring approximately 780,000 years ago. These reversals are a natural process that has taken place over millions of years.
Rocks that have magnetic fields that point south show?
that they were formed when Earth's magnetic field was reversed, with the magnetic north pole being near the geographic south pole. This phenomenon is known as paleomagnetism and is used to study the history of Earth's magnetic field and plate tectonics.
How have Earths magnetic poles reversed many times during Earths history?
Earth's magnetic poles have reversed many times in the past due to changes in the Earth's molten outer core. As the molten metal moves, it generates the Earth's magnetic field. Over time, this movement can cause the magnetic field to weaken, flip, and establish a new polarity. The process of pole reversals is a natural part of the Earth's geophysical history.
What evidence is there for the reversal of the magnetic field of the earth?
Evidence for the reversal of Earth's magnetic field is found in magnetic minerals in rocks that preserve the direction of the field when they were formed. These minerals show alternating patterns of magnetization that suggest the field has reversed multiple times throughout Earth's history. Additionally, studies of sediment cores and oceanic crust have also provided evidence of past magnetic field reversals.
The alignment of iron minerals in rocks when they are formed reflects the fact that Earth's has reversed itself several times in the past?
The alignment of iron minerals in rocks, known as paleomagnetism, provides evidence of past magnetic field reversals on Earth. These reversals have occurred several times throughout Earth's history, as recorded in the rock record. Studying this phenomenon helps scientists understand the history of Earth's magnetic field and geologic processes.
Describe how the polarity of earth's magnetic field is recorded in the sea-floor?
Magnetic minerals in the Earth's crust align with the planet's magnetic field at the time of their formation. When new oceanic crust is created at mid-ocean ridges, these minerals record the direction of the Earth's magnetic field on the sea-floor. This creates alternating stripes of normal and reversed polarity as the sea-floor spreads.
