Can someone please tell me why the magnetic field makes the electrons flow round the coil in a generator? Does the force of the magnetic field have to go in the same direction as the coil?
It is a good, but hard question. Try to google it, or maybe wikipedia got an answer. What I have learned, and it might not be correct, is that electromagnetism will affect the free electrons in a conductor when applying a force as when moving the conductor through the electromagnetic field. Free electrons in the conductor will gather on one side of the wire. When you load this wire the elerctrons can flow back to the other end with lack of electrons. But as long the wire is moving through the electromagnetic field the electron flow will continue.Eisen said:I haven't got an answer yet, can someone please reply with an answer?
For that answer, you'll have to ask the Creator.Eisen said:Why does cutting the lines of the magnetic field cause electrons in the copper wire to be deflected in the right direction?
That gives maximum induced voltage. At other angles, you still get induced voltage, but of lesser magnitude.When the wire goes through the magnet it is at a right angle to the magnetic field-
Direction of movement, direction of magnetic lines, and the induced current are all vector quantities and are all perpendicular to each other: an x-y-z 3-dimensional space.See what I mean? So how do the electrons get pushed up vertically by a magnetic field that seems to be horizontal?

Electromagnetic induction is the process by which a changing magnetic field creates an electric current in a conductor.
Electricity and magnetism are closely related in electromagnetic induction. A changing magnetic field induces an electric current, and a moving electric current creates a magnetic field.
Electromagnetic induction is used in a variety of devices, including generators, transformers, electric motors, and wireless chargers. It is also used in MRI machines, induction stoves, and metal detectors.
Faraday's law of induction states that a changing magnetic field induces an electric current in a conductor. This law explains how electromagnetic induction works and is the basis for many applications of electromagnetic induction.
The strength of the induced current in electromagnetic induction depends on the strength of the magnetic field, the speed of the change in the magnetic field, the number of turns in the conductor, and the material of the conductor. Additionally, the angle between the magnetic field and the conductor can also affect the strength of the induced current.
