The researchers explained that the protective magnetic field surrounding the Earth is so strong that it should
The interplanetary collision was socolossal that as a result of it, pieces of material were formed from which the moon was formed. Scientists have been studying isotopes, meteorites and geology for decades to determine how the moon formed, but the magnetic field hypothesis has not been studied as thoroughly.
The earth generates its magnetic field throughgeodynamo, which requires the planet to rotate at a certain speed and have an internal fluid capable of conducting electricity. The molten iron outer core of the Earth is where the conversion of electrical and magnetic energy takes place.
The field is self-sustaining becausea magnetic field induces a current, and it generates a magnetic field. But how this process arose is poorly understood. In the paper, the authors note that these are key questions to be asked in future research to determine whether a strong field existed before or after the collision.
The field works because of the rapid rotation of the Earth,which is the key to maintaining magnetism. According to the researchers, the dynamo only works if it is maintained and cannot restart due to physical limitations in the Earth's interior.
The authors added that taking into account thisdynamo-limiting can help future researchers to determine the time of occurrence of the Earth's magnetic field. They are also asking for more research, delving into the history of the Earth's field.
