The Earth's magnetic field undergoes changes over time due to variations in the movement of molten iron in the outer core. These movements can cause the magnetic poles to shift positions gradually. Additionally, long-term changes in the Earth's magnetic field can be influenced by external factors such as the sun's activity and interactions with other celestial bodies.
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.
There is no scientific evidence to suggest that the polarity of Earth's magnetic field will change in 2012 or any time soon. The Earth's magnetic field has undergone numerous reversals throughout its history, but these events occur over thousands of years, not within a single year.
Yes, Earth's magnetic field is weaker at the poles compared to the equator. This is because the magnetic field lines converge at the poles, making the field strength weaker in those regions.
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.
The Earth's magnetic field has changed polarity hundreds of times in the geological past. This phenomenon is known as geomagnetic reversal. The frequency at which these reversals occur is not regular, but on average, it is estimated to happen every few hundred thousand years.
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.
sorry I forgot the answer. dummy!
The Earth's magnetic field changes over time because that is the way that God makes it.
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
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.
