What are the two theories that attempt to explain earths magnetic field?
the two theories that attempt to explain earths magnetic field are Dynamo theory--the theory that is believed by the majority of geologists. it says the rotation of the earth causes the liquid core to move in one overall direction, causing the movement of electrical charges, creating the current making the magnetic field. Rapid-decay theory---is believed by the minority of geologists. it makes assumptions about how the earth was formed to calculate how much electrical current would be generated and how much it would have slowed down. =
What is a very likely candidate for the existence of the earths magnetic field?
The most accepted theory for the Earth's magnetic field is that it is generated by the movement of molten iron and nickel in the outer core of the Earth, leading to the generation of a self-sustaining magnetic field through a process called the geodynamo effect.
The dynamo theory states that earths magnetic field is created in layers?
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
The dynamo theory states that earths magnetic field is created in layer as the?
The dynamo theory states that Earth's magnetic field is generated by the movement of molten iron in the outer core of the planet. The fluid motion of the molten iron creates electric currents, which in turn produce the magnetic field that surrounds Earth. This process operates similar to a self-sustaining dynamo, hence the name "dynamo theory."
How does a changing magnetic field produce an electric field according to electromagnetic theory?
According to electromagnetic theory, a changing magnetic field induces an electric field. This phenomenon is known as electromagnetic induction, where the changing magnetic field creates a force that causes electrons to move, generating an electric current.
What causes some material to have magnetic field?
Current theory is that the mechanism for field generation is the "geodynamo". The outer core rotates and conducts energy.
What causes some materials to magnetic fields?
Current theory is that the mechanism for field generation is the "geodynamo". The outer core rotates and conducts energy.
What theory explains changes in the earths crust?
Contenintal Drift theory
What is The theory that explains the source of Earth's magnetic field?
dynamo theory
What was the theory about the earths shape before?
oblong
Which theory states every molecules of magnetic substance is a tiny magnet?
The theory that every molecule of a magnetic substance is a tiny magnet is known as the domain theory. In this theory, magnetic materials are made up of small regions called domains, where each domain consists of multiple atoms with their magnetic moments aligned in the same direction.
What is the theory that explains the source of Earth's magnetic field called?
The source of Earth's magnetic field is best explained by _____.domainsthe dynamo theoryCoulomb's lawelectrostatics
