How is electricity generated using coal and wind?
An electricity generator is basically a magnet spinning inside a stationery coil of copper wire. This produces electricity. Anything that can spin the magnet will work. So wind blowing on the blades of a windmill will turn it, and this produces electricity. Using coal, the coal is burnt and turns water into steam. This steam turns the propellor, which rotates the magnet, and electricity is produced. There are big differences between the two ways of generation. Coal is non renewable, dirty and costly. We have to dig it out of the ground, and mining and then burning it produces a lot of pollution, not least of which is carbon dioxide, which is causing global warming. Wind, on the other hand, is renewable, clean and free!

What are the apparatus used to show that moving magnet conduct electricity?
Volt Metre is the apparatus used to detect the electricity generated. Moving a magnet in or around coil of enamelled copper wire or vice versa will generate electricity. The electricity generated can be detected, by connecting the ends of wires of coil to a Volt Metre. The Voltage generated proportional to the speed of movement and strength of the magnet, and the number of turns of the coil.

Can two electromagnets produce electricity?
Two magnets with different polarities with a coil spinning in between produces electricity. It can be configured as a DC machine or an AC machine. Likewise two electromagnets with different polarities with a coil spinning in between them can produce electricity in the coil but is totally a waste of time and energy. The electricity produced is less than the electricity used in the two electromagnets. It will be similar to a transformer where one coil was supplied with electricity making it an electromagnet, now another coil near it was affected by the magnetism of the other coil and produce an electricity with a voltage higher or lower. Law of thermodynamics states that you can create or destroy energy but only convert it to another form. So the higher the voltage produced in the other coil the lower the current and the lower the voltage the higher the current, plus take into consideration the lost in electric power dissipated or converted as heat.

Why is a magnet useful in generating electricity?
As Faraday discovered, turning a magnet in a coil of wire generates electricity. This is how even today electricity is created, but we use water to turn the magnets in hydroelectricity and so on. It is useful because it is very efficient and it has a mechanical advantage: the force needed to turn the magnet is lss than the force generated by the magnet turning. So basically, to sum it up, the only way to generate electricity is wih a magnet and a solenoid (coil)
