How does moving magnet generate electricity?
magnet moves cause all magnets have an electric field around it]
How electric energy is change to sound energy?
Electric energy is changed to sound energy by a electromagnetic transducer, a speaker. The speaker moves a magnet that moves the air.
Does a coil carrying electric current create a magnetic field?
No, The magnet rotates/moves through the coil, inducing a current into the coil by disturbing the coils magnetic field. A transformer works the exact same way.
What actually moves when an electric current flow?
Electrons move in electron current flow.
What magnet is used to convert sound into electrical signals?
Microphones are used to convert sound into electrical signals.A microphone has 3 parts to it. A diaphragm, a magnet, and an inductor (a coil of wire). The diaphragm and the magnet are attached to each other, while the inductor is coiled around the magnet. Since sound is a pressure wave, the pressure wave moves the diaphragm back and forth. The magnet which is attached to it also moves back and forth in and out of the inductor coil. The motion of the magnet through the coil changes the strength of the magnetic field at the inductor and this causes an electrical current to flow in the inductor.So it is not the magnet itself that converts the sound into electrical signals, it is a 3 step process.Diaphragm turns pressure waves into motionMagnet turns the motion into a changing magnetic fieldInductor turns the changing magnetic field into an electric current.
When a magnet is moved through a coil of wire an electric current is generated in the coil because?
the magnetic field affecting the wire changes as the magnet moves.
What happens to the electric current if the magnet no longer moves in the coil?
The electrical current stops flowing.
When an electric charge moves through a conductor there is an electric in the conductor?
current
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
How can sound be changed into electric current?
The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
When an electric current moves through a long conductor each electron moves?
The free electrons moves through a relatively short distance.
Is it true that when an electric current flows through a long conductor each free electron moves through a relatively short distance?
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
How does electromagnitism work?
The electromagnet can be defined as a magnet created when electric current passes through a conducting medium. Whenever any charged particle moves it creates a magnetic field around its path of travel.
When an electric current flows through a long-conductor each free electron moves?
The free electrons moves through a relatively short distance.
An electric motor turns because the electricity passing through its coils produces?
An electric motor turns because its coils are present between the poles of a strong magnet or electromagnet. Whenever a current passes through a wire in a magnetic field, the wire moves. The electromagnet and the copper coils are arranged in such a manner that when a current passes through the coil an armature linked to the coil rotates.
How does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
Does a generator produce electric current?
