Earth has a magnetic field because of the movement of molten iron and nickel in its outer core. This movement generates electric currents, which in turn create a magnetic field around the planet.

Where the vertical component of earth's magnetic field is zero?

The vertical component of Earth's magnetic field is zero at the magnetic equator, where the magnetic field lines are horizontal. At the magnetic equator, the magnetic field lines run parallel to the Earth's surface, resulting in a zero vertical component.


What is the strength of the Earth's magnetic field in tesla?

The strength of the Earth's magnetic field is about 25 to 65 microteslas.


Earth magnet what?

Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field South pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole). This makes the compass usable for navigation. The cause of the field can be explained by dynamo theory. A magnetic field extends infinitely, though it weakens with distance from its source. The Earth's magnetic field, also called the geomagnetic field, which effectively extends several tens of thousands of kilometres into space, forms the Earth's magnetosphere. A paleomagnetic study of Australian red dacite and pillow basalt has estimated the magnetic field to be at least 3.5 billion years old.


How strong is the Earth's magnetic field and what factors influence its intensity?

The Earth's magnetic field is relatively strong, with a strength of about 25 to 65 microteslas at the surface. The intensity of the Earth's magnetic field is influenced by factors such as the movement of molten iron in the outer core, the rotation of the Earth, and the interactions between the Earth's magnetic field and the solar wind.


How yo find the magnetic field of earth at a particular place?

Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.

What is resion of Earth magnetic field?

The Earth's magnetic field is the result of electrical currents flowing in the earth.


What creates the Earths magnetic field?

Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.


Why does a compass point North?

A compass points north because of the Earth's magnetic field. The magnetic field exerts a force on the needle of a compass, aligning it with the magnetic north pole, which is close to the geographic North Pole.

What makes compasses point to the North pole?

Magnetism. The compass aligns with the magnetic field of the Earth.


What is the magnetic force of this planet called?

The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.


Does the moon have a stronger magnetic field than the earth?

No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.

How does the solar wind cools change in the position of magnetic pole?

Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field S pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole).
