We discovered Israeli wire tapsLebanese media report that blast heard near towns of Houla and Mais al-Jabal that 'was caused by discovery of breach in Hezbollah telecommunications network.' According to report, two cables found - one for listening, one for broadcast.
The discovery of wire is not attributed to a single individual, as it has been used for thousands of years. The earliest known wire was made from copper and dates back to ancient civilizations such as the Egyptians and Mesopotamians. Over time, wire-making techniques have evolved to include various materials like iron, steel, and aluminum.
Passing a magnetic field by a wire induces an electric current in the wire. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 19th century.
The first person to get killed by a lightning strike.
Oersted discovered that an electric current produces a magnetic field, that the magnetic field direction is perpendicular to the current flow, and that the strength of the magnetic field is directly proportional to the current flowing through the conductor.
Michael Faraday discovered electromagnetic induction in 1831 by observing that a changing magnetic field induces an electric current in a nearby circuit. He demonstrated this by moving a magnet through a coil of wire, which created an electric current in the wire. This discovery laid the foundation for the development of electric generators and transformers.
Heinrich Hertz discovered this in the late 19th century when he demonstrated that electromagnetic waves could travel through space without the need for a wired conductor, through his experiments with radio waves. This discovery laid the foundation for wireless communication technologies.

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.
Faraday discovered that wire carrying a current, electrons, has an electromagnetic field around it.
Michael Faraday discovered that a changing magnetic field can induce an electric current in a wire, which is known as electromagnetic induction. This discovery laid the foundation for the development of electric generators and transformers.
Moving a magnet through a loop of wire creates an electric current in the wire. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 19th century. It forms the basis for the working of generators and transformers.
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.
The discovery was that increasing the number of wire coils on an electromagnet results in a stronger magnetic field. This relationship was observed through experimentation and measurements of the magnetic field strength produced by different numbers of wire coils on the electromagnet.
