Let me list my understanding and questions.
1. Electricity is generated by power stations/renewable source
(q)2. How is AC created before going into the step up transformer? Through a alternator?
3. AC current is then delivered into the step up transformer
4. I know a clockwise current = south pole and anti-clockwise = north through a solenoid
5. that creates a magnetic field
(q)6 does the entirety of the top of induced magnet (iron core) become north/south
n n
s s
or is it like
n s
s n
this?
(q)7. p.d. is induced, how? does the magnetic field attract or repulse or move electrons?
8. energy cannot be created or destroyed that means charge is somehow transferred from power st. to p. coil to s. coil (up) to pylons to p. coil to s. coil (down) to houses
(q)9. how is charge transferred when there are no connections between p. coil and s. coil?
