As part of the Apollo mission, scientists concluded that the Moon had no magnetic field for the past 4 billion years, analyzing samples collected decades ago.
To be precise, the analysis includes fragments of lunar rock that formed 3.9, 3.6, 3.3 and 3.2 billion years ago, respectively. Unusually older models claim that there was no lunar dynamo activity at this time. Otherwise, scientists will have proof that there is a magnetic field inside our natural satellite.

How can we say that there was a magnetic field at different positions of the moon? What is important here are the relevant models – in this case, 3-4 billion years old. Next, scientists need to determine if the samples in question have recorded magnetic activity within them.
The Moon currently has a very weak magnetic field 100 times weaker than the Earth
Appropriate provisions in this regard, Available on the pages Scientific progressSuggests that the moon’s surface is relatively stable, although it benefits from the regular blows of the solar wind. Data in the possession of scientists now suggests that the Silver Globe has not had a durable dynamo for 4 billion years. What does this information change? Determining whether our natural satellite had a long-lasting magnetic field in the past is important for understanding how its interior and surface formed.

In terms of magnetic field, the Moon is closer to Mars than to Earth. It is about 100 times older than Earth, while the Red Planet has weak local magnetic fields. In the past, however, Mars was better protected from solar storms and other sources of radiation. If the Moon could muster similar evidence, scientists could more accurately determine the conditions under which it formed and formed.
