What is difference between induced voltage and induced current?
Just as a current flowing through a wire will produce a magnetic field, so a wire moving through a magnetic field will have a current flowing through it. This is called electromagnetic induction and the current in the wire is called induced current. A stationary wire in the presence of a changing magnetic field also has an induced current. A changing magnetic field can be produced either by moving a magnet near to the stationary wire or by using alternating current. A stationary wire in a magnetic field which is not changing will have no current induced in it. You will sometimes see this effect described as induced voltage. Strictly speaking, you will only get an induced current in the wire if it is part of a complete circuit. A wire which is unconnected at both ends will have a difference in voltage between the ends (a potential difference) but current can only flow when the wire is in a circuit. Induced current is used in electricity generation and transformers.Another AnswerThere is no such thing as an 'induced current', only an 'induced voltage'. Current will flow only if the conductor into which the voltage is induced forms part of a closed circuit.
When a conductor is moved through a magnetic field the force of the magnetic field generates what in the conductor?
Yes Ofcourse ,when a curren is allowed to pass through a conductor,"IT IS BEING SURROUNDED BY MAGNETIC FIENLD".... Because it somehow behaves as the electromagnet as per FARADAY LAW OF ELECTROMAGNETIC INDUCTION.............
Why are both negative and positive voltages generated as the magnet passes through the coil?
In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.
Explain what happens when a long straight conductor is moved through a uniform magnetic field at a constant velocity Assuming that the conductor moves perpendicularly to the field?
Interesting question. Because Fleming's right hand rule tells us that a conductor carrying a current perpedicular to a magnetic field will move in a particular direction we know that movement, current and magnetic field are related. So if we take the current away and instead force the conductor to move as described then we would observe a current in the wire. However, you have not said that your conductor is connected in a circuit - in which case the charge carriers in the conductor will tend to one side like a bar magnet.AnswerThe original answer is incorrect. A voltage would be induced into the conductor. No current would flow unless the conductor forms a continuous circuit.
What is the result on the meter reading of clamping the jaws of a clamp-on ammeter around two wires?
If the two wires are on a parallel feed you would read the current through the parallel feeders. If the two wires are "hot " to the load and return back from the load the meter will read zero. The two magnetic fields that surround the wires when a current flows through them will cancel each other. As a result of this there will be no magnetic induction induced into the sensing coil of the clamp on meter.
What is the relation of conductor velocity?
The conductor velocity is directly related to the induced voltage in a conductor moving through a magnetic field. This relationship is described by Faraday's law of electromagnetic induction, which states that the induced voltage is proportional to the rate of change of magnetic flux through the conductor.
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 happens when a conductor is passed through a magnetic field?
When a conductor is passed through a magnetic field, an electric current is induced in the conductor. This is known as electromagnetic induction, a phenomenon discovered by Michael Faraday in the 19th century.
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 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.
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 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.
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.
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the what?
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the length and the speed of the conductor.
Will there be a induced current if the magnet remains at rest?
No, a stationary magnet will not induce a current in a nearby conductor. Movement or change in magnetic field is required to induce an electric current in a conductor through electromagnetic induction.
SI unit of magnetic-induction?
Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.CommentFurther to the original answer, it is a voltage that is induced into a conductor, NOT a current.
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.
