Magnetic field and induced voltage

[Vikas_Madhu]

Can anyone tell me the site or give information on these i have small doubts in that so can anyone give exact answer


When a sinusoidal input is applied to circular coil of N turns what is the magnetic field generated around it and what is the induced voltage in an other circular coil of same number of turns at distance x .

thanks in advance.

or just search google for electromagnetic induction, transformers how they work etc.

as to your second question you really need to put in some numbers to get the answer but the concept seems ok.
