Fluency Practice

Faraday's Law states that the magnitude of the induced EMF equals the rate of change of magnetic flux. Which expression is correct?

$\varepsilon = \Phi_B \cdot \Delta t$

$\varepsilon = \frac{\Delta\Phi_B}{\Delta t}$

$\varepsilon = B \cdot A$

$\varepsilon = \frac{\Delta B}{\Delta t}$
