Magnetic flux

Vedclass · Answer

(A) The unit $VS$ stands for Volt-second $(V \cdot s)$.According to Faraday's law of electromagnetic induction,the induced electromotive force $(e)$ is given by $e = -\frac{d\Phi_B}{dt}$,where $\Phi_B$ is the magnetic flux.Rearranging this,we get $d\Phi_B = e \cdot dt$.The unit of magnetic flux $(\Phi_B)$ is the Weber $(Wb)$.Since the unit of electromotive force $(e)$ is the Volt $(V)$ and the unit of time $(t)$ is the second $(s)$,we have $1 \ Wb = 1 \ V \cdot s$.Therefore,$VS$ is the unit of magnetic flux.
