Not very strong in comparison with a typical small "bar magnet" which has a field strength of roughly 100 gauss.
Earth's magnetic field strength at the surface is about 0.3 to 0.6 gauss.
That's stronger than some planets and weaker than others.
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".
A strong magnetic field has a higher magnetic flux density than a weak magnetic field. This means that a strong magnetic field exerts a greater force on nearby magnetic materials compared to a weak magnetic field. Additionally, strong magnetic fields are more effective for magnetizing materials or creating magnetic induction.
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.
