Do electrons flow better through thin strands of copper? That‘s the only thing I can think of.Thanks for your time and help everyone.
The thin strands of copper are insulated, the electrons do not travel straight through the coil, but rather around and around, thereby increasing the distance in the magnetic field - greatly increases output and efficiency compared to a block of copper.
That would be over-killing. Using spools of copper in small capacity generators are meant to minimize the design to limit the cost, weight, purpose, etc. In larger capacity generators, like in power plants, copper bars are used, as spools of copper become inadequate.
Generating electricity is a somewhat complex subject, but I'll try to simplify it here. When a loop of wire (Conductor) is passed through a magnetic field, a current is induced into the conductor. Therefore, the more loops or conductors that pass through the field, the greater the electrical inductance. If one solid Large strand (Equal to hundreds of smaller strands) were to pass through a magnetic field, it would generate the same amount as one single strand of the smallest wire. Hope you get some clarification out of this.
