Of course that has a great effect since as the magnet strength increase the number of magnetic flux lines increase increasing the induced electromotive force but motion of magnet is needed.

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.
Is induced voltage and induced currrent the same?
Induced voltage is alsocalled ghost or phantom voltage as if you apply a load it vanishes. induced voltage will be potential/electrical pressure. Amperage is the actual flow of current being used, Watts being its calibration of total power used.
How is voltage induced in a conductor?
According to Faraday's law, a voltage is induced in a conductor by a changing magnetic field.
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
Is the process of producing an electric current by moving a loop of wire through a magnetic field?
A current is induced in the conductor by the moving magnetic field (relative to the wire, the field is moving) I guess induction might be the term you are looking for.Another AnswerMoving a magnet through a loop of wire will induce a voltage, not a current, into a coil. If the coil forms a closed loop, then a current will result. But it's a voltage that's being induced, not a current -the current is merely the result of that voltage.
How is the induced voltage of separately excited dc generator affected if the speed increases?
as speed increases, induced voltage increases
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.

Do you add electrical supply voltage and induced voltage of a coil to get total voltage on the coil?
The induced voltage acts to oppose any change in current that is causing it. So, if the current is increasing, then the induced voltage will act in the opposite direction to the supply voltage; if the current is decreasing, then the induced voltage will act in the same direction as the supply voltage.
How can vary the induced voltage in rotor?
You can vary the induced voltage by varing the speed of the rotor.
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.
Who formulated a law for determining the direction of the induced current in a conductor?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current! The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.
Is induced voltage and induced currrent the same?
Induced voltage is alsocalled ghost or phantom voltage as if you apply a load it vanishes. induced voltage will be potential/electrical pressure. Amperage is the actual flow of current being used, Watts being its calibration of total power used.
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!
Do the induced voltage increase in a transformer when the magnetic field strength increase?
Yes, the more voltage you put in the more you get out. If the transformer is a 2 - 1 ratio and you put 240 in you get 120 out and when you put 480 in you get 240 out. Magnetic field strength and voltage have a direct relationship. +++ The field strength is actually a function of current, although as you say, increasing the voltage will increase the current hence the magnetic field.
What is the difference between impressed voltage and induced voltage?
A: impressed voltage is a mechanical connection involved induced has no mechanical connection except for proximity
How is voltage induced in a conductor?
According to Faraday's law, a voltage is induced in a conductor by a changing magnetic field.
