In 1897 JJ Thomson set out to prove that cathode rays originating from a heated cathode (electron gun), were actually a stream of small negatively charged particles called electrons . From Maxwell's theory on electromagnetism he knew that charged particles could be deflected in electric and magnetic fields.. In this final session we will examine several evidences from the earth that show that it cannot be billions of . years old, and that line up with the earth being young. Sodium levels in the ocean.

Earth’s magnetic field can be roughly approximated by that of a dipole tilted at an angle of 11.5 degrees from Earth’s axis of rotation. ~Magnetosphere. Earth’s Magnetic Field. The Earth acts like it has a giant bar magnet buried in it.. The magnetic field of the Earth is caused by convections currents of the molten iron and nickel interior of the Earth.
