A superconductor.
A superconductor is the only material that completely repels magnetic fields, acting as an insulator from magnetism. This phenomenon is known as the Meissner effect, where a superconductor expels magnetic fields from its interior when it transitions to a superconducting state.
Copper has a conductivity of 57 MS/m, whereas Silver has a conductivity of 66.5 MS/m. Bosch Automotive Engineer's Handbook 2nd Ed. 1987 Delta Press ISBN:1-85-226-00-9
Currently, the superconductor with the highest critical temperature ever recorded is Mercury Barium Thallium Copper Oxide or Hg0.2Tl0.8Ca2Cu3O, which has a critical temperature of 139 K at one atmosphere. This superconductor is a type of ceramic copper oxide and its critical temperature was determined in 1995 by Chakoumakos, Dai, Wong, Sun, Lu, and Xin. Apparently, metal-copper oxide ceramic superconductors have high critical temperatures, which might unlock the key of synthesizing a high temperature superconductor that is superconductive under room temperature conditions.
Electrical conductivity is 6.7 Ms/m (mega-siemens / metre) which is approximately the same as 1010 carbon steel. Technetium, cooled to a few degrees above absolute zero, becomes a superconductor. Please see the links.
Pure mercury will exhibit superconductivity at 4.2 degrees Kelvin. It was the first superconductive material that H. Kamerlingh Onnes found in 1911.
American Superconductor was created in 1987.
No. Salt water is a conductor but not a superconductor.
An ideal superconductor has exactly zero losses, thus resistance is zero.
No, water is not a superconductor. Superconductors are materials that can conduct electricity with no resistance at very low temperatures. Water does not have the properties necessary to exhibit superconductivity.
A superconductor floating works by using the Meissner effect, which causes the superconductor to repel magnetic fields. This creates a magnetic field that locks the superconductor in place above a magnet, allowing it to float without any friction or resistance.

yes
Any electrons flowing through a superconductor will show up as a regular electric current.
