How was current produce or induced?
Current is induced and not produced. when an electric wire is passed through magnetic field the current is induced in the electric wire, this electric wire is enamelled copper conductor of a rotor.AnswerCurrent is never 'induced' into a conductor. It is a voltage that is induced. If that conductor is then part of a complete circuit, then the induced voltage will cause a current to flow. The induced voltage will occur even when the conductor is open circuited.
Why is magnetism induced into an iron bar placed near a magnet?
A magnetic field induces an electric current. Hence, by placing the iron bar close to the magnet, a current is induced; and so we are, in effect, creating an electromagnet.
In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
Why there is an induced current in a coil when a coil is rotated between two magnets?
cutting through magnetic lines of force produce electric current.
What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric 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.
What is magnetic effect of electric current?
A magnetic field is induced around any conductor carrying an electric current.As explained in the Oersted Theory.

What is induction of electric current?
According to Farady's law, whenever the flux linking with the coil changes, emf will induce in that coil.Actually the material should oppose the flux changes, that opposition is the induced current. Induced current will set own flux, opposite to that of the flux changes.For further details, refer lenz law.
An electric current can be generated by moving a wire coil in a magnetic?
No, a voltage will be generated, not a current. Current will only flow if the induced voltage is connected to a load.
What determines whether an induced current is a direct current or an alternating current?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
When there is a sudden collapse of a magnetic field in or around a solenoid. what happens?
Electric current will be induced in such a way that the flux of the magnetic field will be constant and thereby the induced current will create magnetic field in the same direction. This is what we call Lenz's law(law of conservation of energy).
Difference between back EMF and induced EMF?
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
