The earth's magnetic field arises from the core of the earth(that we know) but why? Have you ever heard of lodestones? Well they are naturally occurring magnets. They are basically composed of ferromagnetic materials like iron. Their magnetic property arises because the iron stays aligned with the magnetic field lines of the earth leading to a change in the arrangement of their electrons.
But our discussion is for the origin of earth's magnetism. Well the core of the earth is composed of materials like Nickel and Iron, hence the core is sometimes called NiFe. Due to hot temperatures and pressure the electrons in the core are constantly changing positions and hence giving out a magnetic flux. The flux density is what gives the field.
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.
The force that surrounds magnetic objects is called a magnetic field. This field is responsible for the attractive and repulsive forces experienced between magnets and magnetic materials.
A magnetic field can exist without current due to the intrinsic magnetic properties of particles like electrons. In atoms and materials, the alignment of these particles' spins can create a magnetic field. This is known as magnetism and is responsible for phenomena like the Earth's magnetic field.
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
Yes, a compass works by aligning itself with the Earth's magnetic field to determine direction. The needle in a compass is magnetized and will point towards the Earth's magnetic north pole.
Yes.
It is made by the movement of the earths core and magma field
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
because it has the hydro electric power to control the earths magnetic field
The outer core of the Earth is responsible for generating the planet's magnetic field through the motion of molten iron and nickel. This movement creates electric currents, which in turn produce the magnetic field that extends around the Earth.
It is Earths' "Magnetosphere".
earths magnetic field is generated by the circulation of liquid metal.
It is Earths' "Magnetosphere".
= An effect of the magnetic field is "Van Allen radiation belt" =
The Earth's Magnetic field.
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
The strength of Earth's magnetic field is strongest at the magnetic poles, which are not necessarily aligned with the geographic poles. The magnetic field is weakest at the magnetic equator.
