There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.

In a transformer what induces a current in the secondary coil?
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
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.
Why is current produced in a coil if it is placed near other coil containg electricity?
When a coil carrying current is placed near another coil, it creates a changing magnetic field which induces a voltage in the second coil according to Faraday's law of electromagnetic induction. This induced voltage causes current to flow in the second coil, resulting in current being produced in the coil.
What is the induced current in the loop when a magnetic field is applied?
When a magnetic field is applied to a loop, it induces an electric current in the loop.
What are the cause of induced emf?
A change in current causes a voltage to be induced into an inductive circuit, which opposes that change of current. This is because the change in current is accompanied by a change in magnetic flux which 'cuts' the conductors and induces a voltage into them.
Why the induced EMF is negative when the voltage in the first coil increasing?
It's an increasing current, not voltage, that induces an e.m.f. into a coil. The reason that the induced e.m.f. opposes the increasing current is all to do with the Law of the Conservation of Energy.
In alternators the welding current is produced on the?
In alternators, the welding current is produced on the stator winding due to the electromagnetic induction process. When the rotor, which is a magnet, rotates within the stator, it creates a varying magnetic field that induces an alternating current (AC) in the stator windings. This induced current can then be used for welding applications by converting it to the appropriate form and intensity required for the welding process.
Why does rotating the coil in a generator induces an electric?
Rotating the coil in a generator induces an electric current due to electromagnetic induction, a principle discovered by Michael Faraday. As the coil rotates within a magnetic field, the motion changes the magnetic flux through the coil. According to Faraday's law, this change in magnetic flux induces an electromotive force (EMF) in the coil, which drives the flow of electric current. The direction of the induced current is determined by Lenz's law, which states that it will oppose the change in flux that produced it.
What happens when a magnet moves in a coil wire?
When a magnet moves in a coil of wire, it induces an electric current in the wire through electromagnetic induction. This phenomenon is described by Faraday's law of electromagnetic induction. The induced current flows in the wire in response to the changing magnetic field produced by the moving magnet.
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.
Where is an alternator's current induced?
An alternator's current is induced in the stator windings, which are stationary components surrounding the rotating rotor. As the rotor, equipped with magnets or electromagnets, spins within the stator, it creates a changing magnetic field, which induces an alternating current (AC) in the stator windings according to Faraday's law of electromagnetic induction. This induced current is then sent out to power electrical systems or charge batteries.
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.
