Hi Guys,

Just a quick question. Does the number of turns affect the amount of magnetic flux? I know the VCE Physics formula sheet has flux = B x A, but if there is more than one turn in the alternator, can flux = N x B x A where N= number of turns?

So if a question asks you to find the average emf in the coil, when finding the change in flux, will I just make flux= B x A. Then when I use the average emf formula, then I put N=10 of what ever as EMF = =N x (change in flux/ change in time)?

All replies will be much appreciated. Thanks
