To induce a voltage of 1 V, a magnetic flux change of 1 weber per second must occur, according to Faraday's law of electromagnetic induction. The number of lines of magnetic flux corresponds to the number of webers. Therefore, to induce a voltage of 1 V, 1 weber of magnetic flux must be cut in 1 second, which translates to cutting through 1 line of magnetic flux if each line represents 1 weber.

What is the relation between voltage and magnetic flux?
A magnet field is the area surrounding a magnet within which the effects of that field may be observed.A magnetic field is represented by imaginary lines of force that we call magnetic flux. Magnetic flux (symbol, the Greek letter phi) is measured in webers (pronounced 'vay-bers'); the intensity of the magnetic flux is called magnetic flux density which is defined as the flux per unit area, measured in webers per square metre, which is given the special name, the tesla.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
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.
How does an electric generator works?
The voltage was produce by cutting of the magnetic flux by the conductors.

When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
What direction do magnetic flux lines travel from?
Magnetic flux lines travel from the north pole of a magnet to the south pole.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
Does constant magnetic flux in a coil induce a current in it?
Faraday's Law: the E.M.F. induced in a conductor [the current is caused by the E.M.F.] is directly propotional to the rate of change of magnetic flux linkage.A constant magnetic flux isn't changing, so the rate of change is zero and the induced E.M.F is zero. No E.M.F. = no current.
Who discovered magnetic lines of flux?
Faraday, proposed lines of flux and lines of force.
Why alternating current induce voltage across an inductor?
due to change in flux
Why is it important that the core of a transformer pass through both coils?
If it doesn't, you don't have a transformer. The core is where the magnetic flux will pass, which induces voltage on the secondary (voltage applied to the primary winding induces a magnetic flux in the core, which induces a voltage on the secondary winding); If the core is not passed through one coil, it will not induce a voltage in that winding. Leakage flux outside the core can result in some inductive coupling, but the job of the core is to couple the primary winding to the secondary winding.
What are magnetic lines of forces?
Electro magnetic flux which is in maxwells and gauss.
What is the direction of flux in a magnetic field?
The direction of flux in a magnetic field is perpendicular to both the magnetic field lines and the surface it passes through.
If magnetic lines are close what does this mean?
If magnetic lines are close, then the magnetic field has a lot of magnetic lines of force packed together. This translates into a large number of flux lines per unit of area through which they're passing. A large number of flux lines per unit area means a high field density. High flux density means the magnetic field is strong compared to a field where the flux lines are not as close together.
