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.
At what degree does a conductor have to pass through a magnetic field to get maximum induced current?
The induced current is maximum when the axis of the conductor, its velocity, and the magnetic field lines are all mutually perpendicular.
When a conductor is moved in a magnetic field a voltage will be induced on the conductor however current won't flow through the conductor unless the conductor is what?
moving
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!
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.
Does charge inside a conductor exert electric field on another charge placed outside the conductor?
Yes, the charges inside a conductor will rearrange when an external charge is placed near or on the surface of the conductor, resulting in an induced electric field inside the conductor. This induced electric field will influence the external charge's behavior without the need for direct contact between the charges.
What happens when a conductor is placed in a constant electric field?
When a conductor is placed in a constant electric field, the free charges within the conductor will rearrange themselves until reaching equilibrium. This results in the charges accumulating on the surface of the conductor, creating an induced electric field that cancels out the external field within the conductor. The conductor will then remain in a stable state as long as the external electric field remains constant.
An electricity current is induced in a conductor to induce a current in the conductor?
An electric current can be induced in a conductor by moving it through a magnetic field or by changing the magnetic field around the conductor. This process is known as electromagnetic induction, and it is the principle behind how generators and transformers work. The changing magnetic field creates an electric field that causes electrons to move, generating an electric current in the conductor.
Electric current is induced when?
electric current is induced when a conductor (such as a wire) moves through a magnetic field or when there is a change in the magnetic field surrounding a conductor. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 1830s.
How are motion induced electric fields and motional emf related in the context of electromagnetic induction?
Motion-induced electric fields and motional emf are related in the context of electromagnetic induction because both phenomena involve the generation of an electric field due to a changing magnetic field. When a conductor moves through a magnetic field, it experiences a motional emf, which is the voltage induced in the conductor. This motional emf is caused by the motion-induced electric fields that are generated in the conductor as a result of the changing magnetic field. In essence, motion-induced electric fields lead to the generation of motional emf through electromagnetic induction.
How was current produce or induced?
Current can be induced in a conductor through electromagnetic induction, where a changing magnetic field causes a flow of electric current. This can be achieved by moving a magnet near a conductor or by varying the current in one nearby. Alternatively, current can be produced by a voltage source such as a battery or generator that creates a potential difference to drive the flow of electrons.
How is voltage induced in a conductor?
Voltage is induced in a conductor when there is a change in magnetic field passing through it, according to Faraday's law of electromagnetic induction. This change in magnetic field creates an electromotive force (emf) that drives the flow of electric current in the conductor.

When a conductor is moved in a magnetic field a voltage will be induced on the conductor. However current won't flow through the conductor unless the conductor is?
moving
When a conductor is passed through a magnetic field a current is induced in the?
conductor due to electromagnetic induction. This occurs because the changing magnetic field around the conductor induces an electric current to flow through it.
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 the direction of the induced electric field?
The direction of the induced electric field is perpendicular to the change in magnetic field.
