Faraday's Law of Induction

INDUC

Faraday's Law of Induction states that a changing magnetic flux through a coil induces an electromotive force (EMF). Lenz's Law dictates that the direction of the induced current opposes the change in magnetic flux. This is the fundamental principle behind electric generators and transformers.

E=โˆ’NdฮฆBdt\mathcal{E} = -N \frac{d\Phi_B}{dt}

Whiteboard Solver Steps

Step 1

Faraday's Law of Electromagnetic Induction

An electromotive force (EMF) is induced in a coil when the magnetic flux linking the coil changes over time.

E=โˆ’NdฮฆBdt\mathcal{E} = -N \frac{d\Phi_B}{dt}
Step 2

Lenz's Direction Law

The negative sign indicates Lenz's Law: the induced EMF generates a current whose magnetic field opposes the change in flux that created it.
