Two aluminum wheels are located at the sides. Rocky planets such as Earth can have magnetic fields when charged materials inside their liquid cores slosh around. You must use an alternating magnetic field, if set up correctly, you will have a permanent displacement. This condition puts in rotation the liquid mercury being a conductive metal. When no external magnetic field is present, the fluid is not magnetic and the orientation of the magnetite particles is random. This supposedly generated a disruptive magnetic field which was supposedly manipulated with some type of … 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. When an electric current flows through the aluminum conductor, it generates a magnetic field, which rotates the liquid mercury. The mercury is placed inside a wooden disc and at the sides two aluminum wheels and at the center a magnet. When current flows through the two conductors, it generates a strong magnetic field that supports the system. Since Mercury is the only other terrestrial planet we know of with a magnetic field, studying Mercury can help us understand our own planet better. NASA’s MESSENGER spacecraft has detected magnetic signals in Mercury’s surface rocks, and even stronger ones in lower orbit. 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. 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. However, when an external magnetic field is applied, the magnetic moments of the particles align with the magnetic field lines. A magnet is placed at the center. When the current flows through the aluminum conductor it generates a magnetic field. Inside Earth, the liquid core is made of iron and nickel, and because of pressure and heat within the Earth, convection cells occur. In this experiment from Electric Experiments Roobert33, liquid mercury is placed inside a wooden disc. Earth’s magnetic field is thought to originate in its liquid outer core, and so it makes sense that the same would be true for Mercury. Diamagnetism was first discovered when Anton Brugmans observed in 1778 that bismuth was repelled by magnetic fields. Mercury, despite its small size, has a magnetic field, because it has a conductive liquid core created by its iron composition and friction resulting from its highly elliptical orbit. Talc powder was added to make the movements of the liquid more visible. This favorable condition rotates the liquid mercury as it’s an electric conductive metal. The motion of liquid metal deep inside Mercury's core generates the planet's magnetic field, much the same way Earth's field arises. So, you can certainly perturb it - but it will relax. Here we see that all orbitals are full, and all electrons are paired. The Earth generates a magnetic field from the flow of molten metal in its core. At room temperature, the element mercury is not very magnetic at all. $\endgroup$ – Stian Yttervik Sep 2 '19 at 18:47 So to answer your question, because Mercury's has no unpaired electrons you could say it isn't magnetic. The electron configuration of Mercury is [Xe]6s2 4f14 5d10. The motion of liquid metal deep inside Mercury's core generates the planet's magnetic field, much the same way Earth's field arises. I think the mercury is supposed to be in a plasma form, which has mercury ions that would react to an applied magnetic field. Planetary magnetic fields are generated by flows in the hot, liquid iron cores of the planets.Measurements made by Mariner 10 in 1974/75 showed that Mercury also has a magnetic field. The debate about Mercury’s core began in 1974, when the Mariner 10 spacecraft detected a magnetic field around Mercury.
