As per the law of electromagnetic induction whenever the magnetic
linkage of a coil changes a emf is induced in the coil.The emf denotes
the the potential difference between two ends of the coil.what i am
confused about is the value of potential of the ends of the coil with
respect to earth.Symbolically let the ends of the coil placed in a
changing flux be denoted by a and b.The potential of end a of coil
with respect to earth be Vae and that of end b of coil be Vbe. The emf
induced in the coil due to changing flux be denoted by Vemf.Then
Vemf=Vae-Vbe=n*rate of change of flux, which is given by a well known
fromula.
But how to evaluate the value of Vae and Vbe?
i.e if we put a voltmeter between a end of coil and earth what will it
read.
pls give your valuable guidance.
thanks for ur time.
