Faraday discovered that wire carrying a current, electrons, has an electromagnetic field around it.
All electrical circuits produce a magnetic field around the wires when a current is travelling. If we want to generate a large field, we can coil the wire. Such a coil is called a solenoid.
You heat the water in the boiler chamber to produce the steam. The steam under pressure rotates the blades of turbine. You have a shaft attached to the turbine. You have the coils of insulated wires wound around the shaft. This shaft rotates between the powerful magnets to give you electrical energy, through the insulated wire.
LED display has a background produce with LED instead of the convectional fluorescent LED are too big and are only use for big outside panel The term LED TV is misleading and should be understood and LCD with LED backlit
because the air is floating around
yes

There are many different types of power plant but they all produce electricity the same way: by spinning huge magnets around an iron core inside a device called a turbine.
An electromagnet is created by winding a coil of wire around an iron core. Electrical current is passed through the wire, which creates a magnetic field. Something that is electromagnetic is anything that is an electromagnet.
If you mean electrical conduction, that requires electrical charges that are fairly free to move around.
