Transformers.?

I understand the basic workings of a transformer,the questions on them really difficult. This is one of the questions – I’d really like a guided explaination on how to tackle it. An audio-frequency tranformer, designed to operate at frequencies as low as 20Hz is used to transform the 5ohm resistance of a secondary load into [...]

How to solve for the NUMBER OF TURNS in a magnetic coil..?

Hello.. i would like to ask if somebody can answer my question.. i need to know how many turns do we make in our coil.. We have a magnetic wire #32.. And we have a magnet with a strength of 150mT+ but just below 200mT(millitesla) Our magnet has a shape of a semi-circle a bit [...]

Where electrons come from in a power generator?I have been trying to find out this but all they say is..?

All they say is that magnetic inductance makes electrons or charge move but what i want to know is where those electrons come from? does they come from the magnet, the air or the conductor itself. And if you could also explain a little about how this process occurs it would be great. By the [...]
