What causes the magnetic field of the earth?
Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.
What causes the Earth’s magnetic field and how does it protect us?
Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun.
How does the sun affect the Earth magnetic field?
It affects it by the intense clouds of high energy particles that it often contains which are produced by solar storms. When these clouds, called coronal mass ejections, make their way to the Earth in 3-4 days, they collide with the magnetic field of the Earth and cause it to change its shape.
What causes the magnetic field of the sun?
The plasma in the sun, therefore, sets up a complicated system of cause and effect in which plasma flows inside the sun – churned up by the enormous heat produced by nuclear fusion at the center of the sun – create the sun’s magnetic fields. This system is known as the solar dynamo.
Can be caused by solar wind and the magnetic field?
She explains in more detail how the solar wind disrupts our magnetosphere: “As the wind flows toward Earth, it carries with it the Sun’s magnetic field. It moves very fast, then smacks right into Earth’s magnetic field. The blow causes a shock to our magnetic protection, which can result in turbulence.”
What is the source of Earth’s magnetic field quizlet?
The Earth’s magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core.
What is the role of the magnetic field on Earth quizlet?
The Earth’s magnetic field. How does the magnetic field protect earth? It protects Earth from solar wind and radiation otherwise solar wind would strip away the atmosphere. At the poles where field lines are close together.
