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
The magnitude of the voltage induced in a conductor moving through a stationary magnet field depends on the?
The speed of the conductor through the magnetic field, which translates into the number of magnetic lines of force the conductor can cut per unit time, will determine the magnitude of the voltage induced in the conductor. As an additional factor, if a longer piece of wire can be moved through the magnetic field, it will induce more voltage as well. The more speed we can put on the conductor, and the more of the conductor we can move through the magnetic field, the more voltage we can induce in the conductor.
What happens when a wire moves through a magnetic field?
wire will move - there is a force acting on it. it's direction depends upon the orientation of current and magnetic field - a nice way to see this is by looking op a Google picture of Fleming's left hand rule. the force depends upon the strength of magnetic field, current and length of conductor (perpendicular to field) in the magnetic field.
Can a permanent magnet solenoid be modified to work like a permanent magnet linear generator to produce electricity?
Yes, The numerical amount of voltage and current produced (or consumed) by the solenoid is related to the "change in magnetic flux per unit time" For example, consider a permanent magnet with a 0.2 T surface flux density and a coil with 100 turns and an ideal inductor core. Now the permanent magnet is moved from an infinite distance to touching the surface of the coil in a time dT= .1 seconds. The max voltage produced across the coil will be equal to N*dI / dT, in this case 100*.2 / .1 = 200 V. Incidentally that is the peak voltage of a 120 volt RMS wave. This effect relates to the dipole moment and magnetic inertia of a material. For example current carrying copper wire near an iron core will induce a large magnetic flux, in which a percentage of this material's free crystal regions align. Moving a permanent magnet near this core will also produce a changing alignment of the cores crystal lattice, equivalent to a straight wire moving through a perpendicular magnetic field at a velocity. A rectifier may be useful on the output of the solenoid to produce dc.
Working principle of generator?
An electric generator is a device which converts mechanical energy to electric energy. An electric generator basically works on two principles, they are:- 1. Electro magnetic induction: This was first discovered by Michael Faraday this law states that when a electric conductor moved through a magnetic field cutting the electro magnetic waves, a electric charge is produced in the conductor. 2. Flemming's right hand rule: Place your thumb finger, index finger, and your middle finger in such a way that all the three are mutually perpendicular to each other. Here if your thumb points the thrust or force and index finger points the electro magnetic field then your middle finger points the direction of induced current. An electric generator consists of a electromagnet or a huge horse shoe magnet in which an armature is enclosed. The armature is made of copper coils. Now when the armature is rotated, it cuts the electro magnetic waves generated by the magnet and hence as a result of electro magnetic induction electricity is generated in the armature and the direction of the induced current can be found out using the Flemming's Right Hand Rule. And how the electric current produced later is stored and carried out differentiates between AC generator and DC generator
When a magnetic field in a wire are moved near each other the voltage produced is said to be?

moving
Why does a generator work?
When a conductive loop is moved through a magnetic field, an electric current is produced in the wire loop. This is the basis of electrical generators.
Why does moving the magnetic field past the wire induce a voltage?
A good question. When an electron is moved, it will generate a magnetic force. In a permanent magnet, there are a 'magnetic domains' in which a number of electrons have similar spin direction. In an electromagnet, there are, by definition, a number of electrons moving in the same direction. If you do not have a moving electron, you do not have a magnetic field! From this statement, you may deduce that the amazing magnetic loops on the Sun, are generated by currents flowing inside the Sun.

Why is the deflection in the galvanometer reversed when the magnet is moved in and out in a solenoid?
When the magnet is moved into the solenoid, the change in magnetic field induces an electric current in the solenoid. This induced current then creates a magnetic field that opposes the initial magnetic field created by the permanent magnet. This opposing magnetic field causes the galvanometer deflection to be reversed.
An electric current can be genrated by moving a wire coil in a magnetic field?
Yes, an electric current can be generated when a wire coil is moved in a magnetic field due to electromagnetic induction. As the coil cuts through the magnetic field lines, it creates a voltage difference across the ends of the coil, resulting in the flow of electric current. This phenomenon is described by Faraday's law of electromagnetic induction.

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.
What happens when wire is placed within a magnetic field?
Electric current is produced.Nothing until it is moved at right angles{90 degrees) to the magnetic field between it's poles. The faster it moves the larger the voltage measured between the ends of the wire.
