Planetary magnetic fields- The summary (part 2)

How they can drive dynamos
We know that all information of planetary magnetic fields based on indirect measurements which are mostly obtained from the space missions. We also make Earth’s dynamo process as reference to understand other planet magnetic fields, although for the Earth itself there is no certain theory how it can generate a dynamo [...]

Can we predict the earthquake?

Findings could lead to earthquake prediction

New instruments detect small changes in rocks along the San Andreas fault up to 101/2 hours before a temblor. But more research is needed.

U.S. researchers said they were able to measure small changes in the density of fractures along [...]

Planetary magnetic fields- The summary (part 1)

Introduction
The solar system can be defined as the sun with all the planets, satellites and asteroids that move around it. The bodies in the solar system which have radius greater than 1000 km are likely to have dynamos that can generate magnetic fields (Jones, 2007). These bodies are the gas giant planets: Jupiter and [...]

The external magnetic field

The magnetic field of the Earth consists of magnetic fields coming from several sources both internal and external source. The external magnetic field of the Earth is mainly from the interaction between the solar wind and geomagnetic field. The solar wind can be described as the movement of particles particularly H+, Helium and electron which [...]
