You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for water on other planets!

    I wonder if any research has been done into whether that oceanic magnetic field was stronger in early Earth's oceans due to the closer proximity Earth was to the moon... And what that may have done for Earth's early life in terms of protection?

    Yah a huge vanderwalls ionic covalence. Because if you take the pH of a glass of DI water, it changes with the glass reflecting light. So resistance equals distance by volume, if you had a giant pH meter, the ocean waves would modify the total volume pH. Since there's iodine at some depth below of argon, the magnetic water reflecting the current water, making a teleportation of the moon.

    It's clearly not there to protect the planet under the same criteria as the molten core. It's there for another reason and purpose, but what is it that reason? It's not there for nothing. It has another benefit and I'm wondering what it is. It likely also has something to do with the orientation of sonar under the surface. And a myriad of other relational functions and relationships.

    Bitcoin (BTC) has been consolidating since its recent all-time high at $US42,00 and has risen back above $US34,000 at the time of writing. The current correction is currently at 30% already, as Bitcoin’s price has bounced from the $US30,000 region several times. Several periods of accumulation were seen in 2020, where Bitcoin’s price ranged for a period of a few months. Such a period is, in fact needed to build strength for continuation. The primary question is whether such a range-bound construction will now yield the same result. As hard as it trading crypto is way more lucrative and is quite logical if you just study the charts and the support resistance and pay attention to what’s going on, I’m not a pro trader but I was lucky enough to make 5BTC since late last year following the instructions and s!gnals of Mr Henry Lucas who runs guidance for beginners and investors who lack understanding on how trading Bitcoin works to help them utilize the volatility of the cryt0p market and also easily get to him on Whatskp + 1 (405) 489-6879 for crypto related issues.

    How much conjecture has gone into to how much something like this might’ve impacted Mars’ magnetic field? Given that our oceans absorb much of our increased heat, how effectively could we extrapolate the loss of heat with the loss of oceans/water? And then combine those heat losses to cement the end of the former Martian magnetic field?

    by the way ? their satellite cant measure incoherent magnetism !oh 20000 time weaker ? i ll be dam maybe they can have a way to measure incoherent magnetism in the futur ! i would be carefull ! why ? normal coherent magnetism everybody knows null point if more external . but the null point of incoherent magnetism is inward ! up to a certain size. past that shrink ? the incoherent magnetism is outside the incoherent magnet . like at atomic size ! yep you end up with a jumble of coherent magnetism and incoherent magnetism outside the atom ! but the effect is still very strong in the null point of the incoherent magnet outside the atom and the coherent magnetic null point witch rejoint incoherent magnetic null point ! if it does not ? you end up with a null point witch is ..... weird ! it basicly cancel magnetism ! a vacuum of magnetism ! ( lack of magnetism ) it is weird ! i would be carefull because 100% nothing love to be reified with 100% something since human have not played much with the vaccum of magnetism ( total lack of magnetism ) we do not exiactly know how electricity or magnetism behave on heart ! naza likely know since they re in space but maybe not since they re on a space staTION

    If our earth core magnetic field and our oceans also create magnetic fields it stands to reason that they interact with each other, the stronger field dominating the weaker. Therefore ocean currents over time which help cause our weather patterns will be impacted greatly if and when our core magnetic field reverses which seems to be happening,g now....our weather will be come more erratic and unusual so will life as seen by the radical behavior of humans lately.

    However, a flow/current of molten metal or ocean does not coincide with an electrical current, cause in sum both are electrically neutral.

      @Levi Howell You can even have a magnet several thousand times stronger than earth in your pocket and the compass will still point north. This is because the field quickly becomes weak with distance (field falls off inversely with the cube of the distance at large distances). The earth is huge in comparison, so we are not far away from it. We are right at the surface of this weak ball magnet.

      @hpekristiansen how come a compass doesn’t point towards the local junk yard with the really strong magnet to pick up metal? That magnet is more powerful than the earths but it’s pull doesn’t influence anything other than what’s in its immediate area. Is it bc the earth is a really big but weak magnet and the one at the junkyard is small but really strong?

    I think that Ganymede and Io have the liquid metal magnetic field

    It's not the only type of magnetism. There's also... Animal magnetism. ;-]

    Like most of my favourite channels, it wouldn't seem like this one has ever been censored.

    If a magnetic field by salt water is 20,000 times weaker than one made by rock, how could you ever expect to distinguish it from the regular magnetic fields? Sounds like a really crappy way to tell about water

    I wonder if we will someday be able to investigate this weaker magnetic field in relation to weather systems. Might it affect the formation of thunderstorms? Or be a contributing factor to even larger weather events like hurricanes?
