Tell me how by the rotating copper coil?

Electricity is NOT produced by an electro-magnet, electricity creates an electro-magnet. Wire is wrapped around a big round slab of steel. Electricity flows through the wire and turns the slab into a temporary powerful magnet. Copper coil may or may not be used and is stationary, not rotating. It is the negative, or receiving coil.
(Electric power provided by a generator mounted in the crane used to pick up the steel with the electro-magnet.)
OK?...............OK.
Now...an electric generator is built basically like an electric motor, only slightly different. The Armature has spaces filled (wrapped) with electric wire (the copper coil) and spins between two magnets (wrapped around the edge with wire.) creating electricity.
A generator needs a motor the make them produce electricity. An electric motor needs electricity to run, but is built similar to the generator.
A generator, for some odd reason, will not make enough electricity to power an electric motor to run it and make enough extra power to use for anything else. Weird but true, I hear.
OK?.............OK.

You seem to have 'electromagnet' and 'generator' confused.
In an electromagnet, current moving through a coil causes a magnetic field to be generated.
In a generator, a coil of wire moves through a magnetic field and (in accordance with Maxwells Laws) a current is induced in the coil.

Copper and conductive metals in general have thermally excited electrons that form the electric current when a voltage is applied. Free electrons moving in a magnetic field experience a force that causes them to move in a perpendicular direction. Likewise, the carrier electrons in the wire experience the same effect, thereby generating a current and a corresponding voltage.

when a current carrying conductor is placed and rotated then an emf is produced in the conductor.This produced emf is then passed through a circuit where the load is connected to it.
the rotation may be electro magnet or current carrying conductor.
Hope u will understand

It is a law when metal coil are cutting magnetic field, they are producing voltage

when electicity is passed through a piece of iron, it becomes magnetic so when a magnetic field is applied, it becomes electric. so simple!
