A recent study reveals that thousands years ago moon had an active magnetic field which was comparatively stronger than the Earth’s.
The research printed in 4th December issue of Journal Science, gave some insight about the internal structure and origin of the moon. However, it also give birth to new questions regarding the entire planetary magnetism
The research unveils that a molten liquid core produces the magnetic field of the Moon. Undoubtedly, the field is not present around Moon anymore. However, remnants of these magnetizations are discovered from lunar rocks.
Benjamin Weiss, a professor of the Massachusetts Institute of Technology stated that the study confirms that Moon had a dynamitic magnetic field nearly 4.25 to 3.56 billion years ago.
The crystallization of an inner liquid metallic and the rotation of the solid layer of the moon formed that magnetic field. Scientists named it as geodynamic that transform the planet into a huge dipole magnet.
Sonio Tikoo, co-author of the study informed that dynamous is an outcome of a course generally known as induction. Induction usually takes place when the entire energy of planetary fluids turns into a magnetic field.
The groundbreaking discovery of the magnetic field is quite astonishing for researchers since the whole mass of the Moon is equivalent to one percent of the Earth.
Furthermore, the study to some extent verifies the giant impact theory related to the creation of the Moon.
