What is the 3 things that oersted discovered about the relationship between electricity and magnetism?
wire , copper rod en magnetic wire
Who discovered that electrical currents do not need an electrical wire to flow through?
Thomas Edison
Who discovered that electrical currents do not need electrical wire to flow through?
The first person to get killed by a lightning strike.
Who discovered electromagnetic force?
Hans Orsted first discovered that when an electric current was run through a wire and put close to a compass, the needle moved toward it. Although, he had no idea what that meant. Michael Faraday, built on his work and found that when an electric current runs through a wire, a magnetic field is produced around the wire. He also found that an electric field is around a wire it produces an electric current. The direction of the current depends on which direction the field is going in. The faster you move the electric field the stronger the current.
Who discovered Saturn moons?
The first person to discover Saturn`s moons was Christian Huygens in 1655. The following moons discovered in order are: Titan Discovered:1655 Discovered by:Christian Huygens Iapetus Discovered:1671 Discovered by:Giovanni Cassini Rhea Discovered:1672 Discovered by:Giovanni Cassini Tethys Discovered:1684 Discovered by:Giovanni Cassini Dione Discovered:1684 Discovered by:Giovanni Cassini Enceladus Discovered:1789 Discovered by:William Herschel Mimas Discovered:1789 Discovered by:William Herschel Hyperion Discovered:1848 Discovered by:William Lassell Phoebe Discovered:1898 Discovered by:William Pickering Janus Discovered:1965-1966 Discovered by: Audouin Dollfus Epimetheus Discovered:1966 Discovered by:Richard Walker Helene Discovered:1980 Discovered by: Pierre Laques Telesto Discovered:1980 Discovered by:Bradford Smith Calypso Discovered:1980 Discovered by:Dan Pascu Prometheus Discovered:1980 Discovered by:Stewart Collins Pandora Discovered:1980 Discovered by:Stewart Collins Atlas Discovered:1980 Discovered by:Richard Terrile Pan Discovered:1981 Discovered by:Showalter Other astronomers:Kevin Beurile, Brett Gladman, Matthew Holman and others.

Does luigi galvani had achievements in his inventions?
During a random experiment on November 6, 1787, Galvani discovered that a frog muscle could be made to contract by placing an iron wire to the muscle and a copper wire to the nerve.

Under what circumstances can an electrical charges produce a magnetic field?
Faraday discovered that wire carrying a current, electrons, has an electromagnetic field around it.
What was the Edison Effect?
The Edison Effect is a fact about heated metal wire- discovered by a British scientist, Frederick Guthrie, in 1873, but named after Edison when the latter independently discovered it in 1880- that it will emit a current of negative charge into a vacuum, and the size of this current depends on the voltage across the metal wire. It states that a voltage across a wire results in a vacuum emission of current is the basis for the vacuum tube, an invention that Edison could have easily developed but decided not to pursue.
True or false an electromagnet must include a coil of wire?
A magnetic field is induced by pushing current though a wire; so you could consider a straight wire an electromagnet. Using more coils will strenghten the electromagnet, though, so a straight wire version will be very weak comparitively.
What did Michael Faraday do when he discovered changing a magnetic field created an electric current in a wire?
Investigate the phenomenon thoroughly, quantitavely as well as qualitatively, and publish his results appropriately.
