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.
What else can I help you with?
Passing a magnetic field by a wire creates a what?
Passing a wire near a magnetic field induces an electric current in the wire.
Who discovered that electrical currents do not need electrical wire to flow through?
The first person to get killed by a lightning strike.
What is the 3 things that oersted discovered about the relationship between electricity and magnetism?
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.
How did Michael Faraday use to discover electricity?
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.
Who discovered that electrical currents do not need an electrical wire to flow through?
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.
Who first discovered that electricity could be made with a magnet and a coil of wire?
Michael Faraday
Passing a magnetic field by a wire creates a what?
Passing a wire near a magnetic field induces an electric current in the wire.
Discovered that a current in a wire can produce magnetic effects?
Faraday. Check his Wiki entry.wrong it was Oersted
Who discovered that electric current going through a wire can create a magnetic field?
Hans Christian Ørsted
Who discovered that electrical currents do not need electrical wire to flow through?
The first person to get killed by a lightning strike.
What is the 3 things that oersted discovered about the relationship between electricity and magnetism?
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.
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.
Who discovered a magnetic field can produce an electric current?
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.
Electromagnetic Induction states that moving a magnet through a loop of wire creates what?
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.
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 was discovered that provides evidence of a cause and effect relationship between the number of wire coils on an electromagnet and magnetic field?
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.
