The discussion revolves around the nature of Earth's magnetic field, its potential charge, and its strength. Participants explore the relationship between electric and magnetic fields, as well as the implications of Earth's core composition on these fields.
Participants express multiple views regarding the nature of Earth's charge and the specifics of its magnetic field strength. The discussion remains unresolved with no consensus on certain aspects.
Some claims about the strength of the magnetic field depend on distance from the core, and there are unresolved questions about the implications of Earth's charge and its effects on free charges in the atmosphere.
what is the strength of this magnetic field? towards the Earth of out " the force"?Comeback City said:Earth has an electric field, but has no net electric charge. The upper atmosphere is positively charged, but the surface is negatively charged.
Earth does have a magnetic field caused by the iron in the core. This magnetic field helps protect us from a great deal of solar radiation.
The strength varies depending on the distance from the core... the magnetic field will be at its strongest when it’s closest to the core, where the abundance of iron is, and will weaken as your travel away from the core. It’s about 50 times stronger at the core than the surface.mohammed El-Kady said:what is the strength of this magnetic field? towards the Earth of out " the force"?

No problem!mohammed El-Kady said:thank you
The Earth's magnetic field is quite weak ... The magnitude of the Earth's magnetic field at its surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss)https://en.wikipedia.org/wiki/Earth's_magnetic_fieldmohammed El-Kady said:what is the strength of this magnetic field? towards the Earth of out " the force"?
