Due to its physical properties and relative chemical inertness, liquid mercury is absorbed very poorly through intact skin and the gastrointestinal tract. [132] Mercury vapor is the primary hazard of elemental mercury. As a result, containers of mercury are securely sealed to avoid spills and evaporation.
Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...
[12] [13] 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. [14] It is theorized that the Moon once had a magnetic field, based on evidence from magnetized lunar rocks, due to its short-lived closer distance to ...
The new data collected by a space probe indicates Mercury's magnetic field could be 3.9 billion years old or some 400 million years older than even Earth's own magnetosphere. In one of its final ...
Mercury's magnetic field tends to be stronger at the equator than at other areas of Mercury. Like Earth's, Mercury's magnetic field is tilted, [9] [23] meaning that the magnetic poles are not located in the same area as the geographic poles. As a result of the north-south asymmetry in Mercury's internal magnetic field, the geometry of magnetic ...
Mercury was used as the main material of early deformable liquid-mirror telescopes because of its high reflectivity and low melting temperature. However, as a magnetic liquid, it had problems. However, as a magnetic liquid, it had problems.
Mercury has an observed magnetic field, which is believed to be generated within its metallic core. [28] Mercury's core occupies 85% of the planet's radius, making it the largest core relative to the size of the planet in the Solar System; this indicates that much of Mercury's surface may have been lost early in the Solar System's history.

Mercury relays consist of a vertical (usually glass) tube containing liquid mercury. They have isolated contacts at the bottom of the tube and partway up, usually in a side arm of the glass. The relay works by displacement. A pool of mercury fills the lower portion of the tube, but is insufficient to bridge the contacts.
