Question

To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as

Answer 1

Answer: $V_{\epsilon}\propto \frac{d\phi_{B}}{dt}$

Explanation:

A direct proportionality means a linear relationship between two variables and rate of change means an application of derivatives. Hence, the mathematical model is:

$V_{\epsilon}\propto \frac{d\phi_{B}}{dt}$
