How exactly can magnets generate electricity

The most fundamental of magnetic fields creates an electric current:

A point charge in a uniform magnetic field will then have a force that is perpendicular to the direction of the motion of the point charge.
When there is a relative movement (change) between multiple point and magnetic charges, there will be an electric current.
An electron is also an electric charge, so it is also subjected to a force of magnetic field. In metal, there are many free electrons. When there is a change (variation) in the magnetic field and those electrons, the metal containing electrons will have an electric current.
There are two models:

Variable magnetic field and fixed coil
The coil (wire frame) varies and the magnetic field is fixed.

This is a moving wire frame model:

Current generators use rotating magnetic fields.

Magnetic Generators and the Difference Between Permanent Magnets and Electromagnets

Permanent magnets can be made out of many different naturally occurring substances of which magnetite is the most powerful. They can also be made out of synthetic substances such as neodymium. A neodymium magnet is the strongest type of permanent magnet and is sometimes described as a super magnet.
The electromagnet was invented in 1825 by William Sturgeon, a British electrician. He demonstrated that a seven ounce piece of iron that was wrapped around with wires and had a small electrical current running through it could lift nine pounds of metal.
An electromagnet becomes magnetic only when an electrical current flows through it and a generator that uses electromagnets or "field coils" requires a flow of electricity through the electromagnets for the device to work. If there is no flow of electricity through the wires then it does not work.
The magnetic generator however uses the rotating magnets to generate electricity in the first place. It generates more energy than is required to keep the magnets rotating and so you can use the excess to power your home.

Use a Magnetic Generator to Make Your Own Inexpensive Electricity Easily

If you want to generate your own inexpensive electricity, a magnetic generator is how you are going to do it. Before that, though, find out how exactly this power is created, and how you can do it. To begin with, you have to realize that the generator must power itself before your appliances. The amount of electricity that you get from this machine will be determined by just how strong the magnet is. It costs no money to use it. This is provided that you can start the machine in the first place. Once you do, you will have a limitless supply of energy for your home.
