magnetic flux used to generate power, Types & grades of magnets, changing magnetic flux to generate more power?
ok so if i put coils of wire between magnets the moving magnetic flux between the N magnet on one side and S magnet on the other side of the coiled wire will generate power, correct? If i wanted to try and generate more power would i need the magnetic flux to be stronger or weaker? Would stronger or weaker magnets be needed tp generate more power. Would using more magnetics generate more power? would using a certain type of wire for the coils help generate more power? what about using different types of magnets ( ferrite, SmCo, NdFeB, Neodymium magnets)?
also would a grade 8 magnet be stronger or weaker then a grade 3, what are the grades of magnetic showing? Any extra simple explanation of magnetic flux would be helpful as well, i don't understand it as well as i should
I know this is a really long multi part question but any help would be appreciated
The bottom line answer to your question is that if you increase the rate of change of the magnetic flux you will increase the induced emf.
Now magnetic flux is defined as N*B*A*cos(omega*t) where N is the number of turns; B is the magnetic field, A is the coil area, and the cos term defines the rotational rate.
The emf is the time rate of change of flux. So here is the key it is not the flux that induces an emf, it is the change of flux that induces the emf.
So the more rapidly you change any of the above parameters the greater the induced emf.
