What is happening to earths magnetic field?
In early 2014, scientists have discovered that the Earth's magnetic field has been weakening for some time. This could eventually lead to the switching of the Earth's magnetic poles.
What is a very likely candidate for the existence of the earths magnetic field?
Scientists are about as certain as they could get in deciding that it is due to the rotation of the earth's iron and nickel core.
Earths magnetic field does not affect what?
Other planets
How can scientists tell when changes occur in earths magnetic field?
Scientists follow the magnetic field lines of the earth and measure them regularly. They will compare the earlier measurements and note the changes in position of the magnetic axis and decide if it is changing or not! Also if there are sudden changes observed in magnetic field lines bec of solar flares from sun. Magnetism is an interesting chapter! learn more by watching and subscribing to this space @PhysicsFusion-sm3tr Hope this helps
A current in a long straight wire produces a magnetic field. These magnetic field lines?
The magnetic field lines are arranged circularly around the wire.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
What do scientist produces earths magnetic field?
Its molten iron core.
Why do scientists think the earths core contains iron?
Iron is magnetic which forms the Earth's magnetic field.
Why do scientists believethat the inner core is the source of earth's magnetic field?
The core is a dense chunck of metal that influence the earths magnetic field.
What produces earths magnetic field?
Scientists think that the Earth's magnetic field is generated by movements in the liquid outer core. (exact e2020 answer help out you wiki answers shortcuts!!)if you want a more serious answer i suggest looking up the "dynamo theory"
Why do scientists think that earths' magnetic field has not always pointed north?
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
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.
Does lightning produces magnetic field?
Yes, The movement of electrical charges produces a magnetic field
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
Is earths core a source of earths magnetic field?
Yes.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
