Induced Voltage Calculator

Formula

The formula to calculate the induced voltage is:

\[ V = -\frac{\Delta \Phi}{\Delta t} \]

Where:

\( V \) is the induced voltage in volts.
\( \Delta \Phi \) is the change in magnetic flux in webers.
\( \Delta t \) is the change in time in seconds.

What is Induced Voltage?

Induced voltage is the voltage generated in a circuit due to a change in magnetic flux through the circuit. This phenomenon is described by Faraday’s Law of Electromagnetic Induction, which states that a time-varying magnetic field will induce an electromotive force (EMF) in a closed circuit. The negative sign in the formula represents Lenz’s Law, which indicates that the induced EMF will always work to oppose the change in magnetic flux that produced it.
