Sulphur and oxygen could also be in the outer core.
The outer core remains in constant motion due to convection and Earth's rotation.
Sulfur and oxygen could also be present in the outer core.
Also, the outer core is constantly moving, due to Earth's rotation and convection.
Earth's magnetic field is generated by currents flowing in Earth's outer core.

Earth owes its magnetic field to its molten outer core, which is made mostly of iron and nickel.
Like the outer core, the inner core is composed primarily of iron and nickel and has a radius of~1,220 km.
The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.
Now, fluid motion in the outer core moves molten iron(i.e., a conducting material) across an already existing, weak magnetic field.
Chemically, Earth can be divided into the crust, upper mantle,lower mantle, outer core, and inner core. .
S-waves don't penetrate the outer core, so they're shadowed everywhere more than 104° away from the epicenter(from USGS).
So, a field weakening over theAmerican continent would mean that the flow in the outer core below America is slowing down.".
Outer core The upper or outermost part of the Earth's core extending from 2,900 to 5,100 kilometers below the surface.
The inner core has an estimated radius of 1,220 km, while the outer core extends beyond it to a radius of about 3,400 km.
This occurs mostly because the inner core cannotdissolve the same amount of light elements as the outer core.
Eventually, the inner core willprobably grow large enough that convection in the outer core is no longer efficient, and the magnetic field will fail.
In particular, as the inner core grows,the heat released during solidification drives convection in the fluid in the outer core.
The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to that of the inner core. .
Or, maybe as the inner core solidified after Earth formed,the oxygen concentration in the outer core increased, the researchers said.
The average magnetic field strength in Earth's outer core is estimated to be 25 Gauss(2.5 mT), which is 50 times the strength of the magnetic field measured on Earth's surface.
This much is evident: The blobs begin thousands of miles below Earth's surface,where the planet's rocky lower mantle meets the molten outer core.
It is generally believed that convection in the outer core, combined with stirring brought on by the Earth's rotation gives rise to the Earth's magnetic field via a procedure described by the dynamo theory.
In 2018, the first successful attempt is made to retrieve samples from Earth's mantle,the part of the planet that lies between the crust and the outer core.
The Earth's inner core isthought to be slowly growing as the liquid outer core at the boundary with the inner core cools and solidifies due to the gradual cooling of the Earth's interior(about 100 degrees Celsius per billion years).
And then in 1937, Danish seismologist Inge Lehmann went a step further anddetermined that within the earth's liquid outer core, there is a solid inner core. .
Due to the temperature difference between the Earth's surface and outer core, and the ability of the crystalline rocks at high pressure and temperature to undergo slow, creeping, viscous-like deformation over millions of years, there is a convective material circulation in the mantle.
According to researchers Mercury's magnetic field is generated by the same“dynamo” process as the Earth's, driven by the roiling of electrically conductive,liquid metal in the planet's outer core.
The team's findings suggest the moon possesses a solid, iron-rich inner core with a radiusof nearly 150 miles and a fluid, primarily liquid-iron outer core with a radius of roughly 205 miles.
The solid inner core is too hot to hold a permanent magnetic field(see: Curie temperature)but probably acts to stabilise the magnetic field generated by the liquid outer core.
