In 1845, Michael Faraday demonstrated that it was a property of matter and concluded that every material responded (in either a diamagnetic or paramagnetic way) to an applied magnetic field. This experiment is … The debate about Mercury’s core began in 1974, when the Mariner 10 spacecraft detected a magnetic field around Mercury. Talc powder was added to make the movements of the liquid more visible. I think the mercury is supposed to be in a plasma form, which has mercury ions that would react to an applied magnetic field. A ferrofluid or ferromagnetic fluid is a liquid that becomes strongly magnetized in the presence of a magnetic field.. A process for making a ferrofluid was invented in 1963 by NASA's Steve Papell to create liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field. Mercury's ancient magnetic poles were far from the location of its poles today, implying its magnetic field, like Earth's, changed over time, a new study says.
However, the eddy currents are dissipated by resistance in the metal, allowing the metal to fall toward the magnet, just somewhat slowed.
A liquid magnet, or ferrofluid, is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier. In this experiment from Electric Experiments Roobert33, liquid mercury is placed inside a wooden disc. This favorable condition rotates the liquid mercury as it’s an electric conductive metal. It has a very small, negative magnetic susceptibility, meaning that when you put mercury in a magnetic field, it magnetizes just a little tiny bit in the opposite direction. This can be understood in a general way as follows: the charged particles moving around the ring act as a current that in turn sets up a magnetic field around the ring. So to answer your question, because Mercury's has no unpaired electrons you could say it isn't magnetic. NASA’s MESSENGER spacecraft has detected magnetic signals in Mercury’s surface rocks, and even stronger ones in lower orbit.
If you imagine the earth as a giant "electric motor" styled, liquid metal flowing around a solid core to create our magnetic field. Even if some turbulent liquid flow gets going in the liquid mercury, I don't see how it could be sustained without some additional energy source. So a mercury drop should fall, roughly similarly to other pieces of metal. Inside the container liquid mercury is poured in a weight of just over 1 Kg. You must use an alternating magnetic field, if set up correctly, you will have a permanent displacement. This supposedly generated a disruptive magnetic field which was supposedly manipulated with some type of … A spacecraft called BepiColombo, which is a joint mission from Europe and Japan, is on its way to Mercury right now and will arrive in 2025.
Inside Earth, the liquid core is made of iron and nickel, and because of pressure and heat within the Earth, convection cells occur. I encountered information describing two hemispherical containers of frozen mercury that were electrically charged on a massive scale and couter-rotated at an unknown rpm.
The mercury is placed inside a wooden disc and at the sides two aluminum wheels and at the center a magnet. The magnetic field of these currents will repel the magnetic field already there.
