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.

Can a round magnet produce electricity if it's rotating?
The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
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 does a magnet create electricity?
It is not the magnet alone, but the movement of a conductor (wire) in a magnetic field will induce a voltage (and a current, if it is connected in a circuit).
How do you generate electricity from a turbine?
A wire moving in a magnetic field will automatically produce an emf (a voltage).
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
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 is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.
Can a magnetic field induce voltage in another nearby conductor?
A: Believe it or not that what a transformer does

Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
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.
What do you create if you move a conductor through a magnetic field?
You would induce a voltage from one end of the conductor to the other.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
Why does a transformer require alternating current?
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
