What causes the magnetic field?
Which magnetic field? If you're talking about the earth, the magnetic poles have switched polarity in the past. The earth is not a solid magnet, it is a liquid, specifically molten nickel. When the molten nickel shifts the magnetic field of the earth can change.
How is the earth's magnetic field created?
A few % of the magnetic field comes from the stream of charged particles coming from the Sun. This is why the magnetic field varies greatly in Polar Regions during a sunspot storm.The majority of the field is generated deep inside the Earth by electrical currents in the liquid part of the outer core. The nett result of these currents generates a magnetic field.The Curie Temperature of magnetic materials ensures that there are no magnetic materials deep in the Earth.
What causes the magnetic compass to react with a magnet?
The compass needle is a small bar magnet balanced on a pin. It swivels freely on this balance point. This is how it can align with the magnetic field of the Earth to show what direction magnetic north is. When you introduce another magnetic field, like from a magnet in close proximity, the needle will align with these local fields since their field strength is stronger than Earth's magnetic field - locally.
What causes the part of earths magnetic field called the magnetosphere to exist?
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with one pole near the north pole and the other near the geographic south pole. The Inner Van Allen Belt & Outer Van Allen Belt cause the magnetic field.
How does a compass needle respond when a compass needle is placed within a magnetic field?
A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the compass will deflect, and realign itself along the north/south axis of the SUM of the fields.
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
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.
Where does the convection occur that causes the Earth's magnetic field?
This happens in the earth's core.
What is the major process that is thought to produce the Earth's magnetic field?
The convection in the outer core, along with rotation of Earth that causes rotation of the outer core, initiates a flow of electric current in the core. This flow of current within the core produces and sustains Earth's magnetic field.
How is earth a magnetic field?
The earth's magnetic field is caused by the fact that the earth has a moltern iron core. When moltern iron spins it causes an electric field. This causes an electromagnetic field. Some planets are too large or too small for the iron in their core to be molten.
The convention that causes earths magnetic field happens in earths?
core
What causes Earth's magnetic field to have the shape it does?
As you might already know, a magnet is the most powerful at it's ends. So what the inner core of the Earth's magnetic field does is that it surround the Earth. Thank you.
What are the causes of magnetic fields?
Earth's magnetic field is produced by the dynamo effectin the liquid metal outer core.
Does Uruguay have a magnetic field?
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
What causes Jupiter's magnetic field?
What causes it's magnetic field is the dynamo effect.
