Jupiter has a magnetic field caused by?
The dynamo effect.
Does Mercury have a magnetic field?
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)
Why does mercury have a strong magnetic field?
Mercury's strong magnetic field is believed to be generated by a liquid iron core that undergoes slow rotation, creating a dynamo effect. This process generates a magnetic field that is proportionally stronger relative to the planet's size compared to other planets in the solar system.
How does a solar storm and solar flare affect earth?
Magnetic Storms have a severe affect on our technological and electrical infrastructure, both in space and on the ground. Usually Earth's magnetic field, generated by the dynamo under earth's lithosphere, protects us from magnetic disturbances, but severe magnetic storms have in the past knocked out power grids in the entire province of Quebec. Magnetic Storms would have a severe effect, and would likely, en masse, shut down large amounts of current human grids and technological infrastructure, as concluded by the National Academy of Sciences.
How does the outer core produce the earths magnetic field?
The Earth's outer core is composed of molten iron and nickel, which creates a fluid dynamo effect as it moves due to convection currents and the rotation of the Earth. This movement generates electric currents, which in turn produce magnetic fields. The combined effect of these magnetic fields results in the generation of the Earth's overall magnetic field, which extends into space and protects the planet from solar radiation. This geodynamo process is crucial for maintaining the stability of the magnetic field over geological timescales.
In what layer is earths magnetic field produced?
Earth's magnetic field is primarily generated in the outer core layer of the planet. It is believed that the convection of molten iron and nickel within this layer, combined with the Earth's rotation, creates a dynamo effect that generates the magnetic field.
What causes the earths magntic fied?
Dynamo Effect
Jupiter has a magnetic field caused by?
The dynamo effect.
Where in the Earth is the magnetic field produced?
The Earth's magnetic field is believed to be primarily generated by convection currents in the liquid outer core composed of iron and nickel. This motion produces a dynamo effect that generates the magnetic field.
What is major cause of the earths magnetic field?
The field is generated by earth's large iron core.
How can somethings magnetic field like a tokamak not affect the earths magnetic field?
Because it is far too small to have any effect. The Earth's magnetic field is thought to be generated thousands of miles underground by moving rivers of iron.
Why does the earth have a magnetic field when some planets don't?
The Earth's magnetic field is generated by a process called the dynamo effect, which is driven by the movement of molten iron and nickel in its outer core. Not all planets have the necessary conditions, such as a molten core and sufficient rotation, to generate a magnetic field.
What occurs when a rapidly rotating conductor is stirred by convection to produce a magnetic field?
When a rapidly rotating conductor is stirred by convection, it generates a phenomenon known as a dynamo effect. This effect causes the motion of the conductor to induce electric currents, which in turn create a magnetic field. The resulting magnetic field can enhance the overall magnetic properties of the system.
Where does earth's magnetic field come from and how does it protect earth from solarwinds?
Earth's magnetic field is generated by the churning of molten iron in the outer core of the Earth. This generates a magnetic dynamo effect. The magnetic field acts as a shield against solar wind by deflecting charged particles from the sun, preventing them from stripping away Earth's atmosphere.
What is one result of convection currents in earths outer core?
One result of convection currents in Earth's outer core is the generation of Earth's magnetic field. As the hot, molten iron in the outer core moves in a circular motion due to convection currents, it creates a dynamo effect that generates the magnetic field.
Does Mercury have a magnetic field?
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core.

What characteristis of earth causes magnetic field that surrounds us?
The cause of the magnetic fields around the earth is the earth's rotation and the convection of electrically conductive molten rock deep inside the Earth. The Earth rotates about an iron core, this produces an induction current that generates a series of magnetic flux lines that comprise the magnetic field. Because the Earth and it's core rotate at different speeds the electromagnetic force is strong. This is called a dynamo effect (the same effect as a simple generator with permanent magnets that powers for example the lights on a bicycle).See article on the dynamo effect by following the link below: Sources and related linksRead more: How_is_earths_magnetic_field_created
