# Lenz's Law

on . Posted in Electromagnetism

Lenz's law, abbreviated as $$\epsilon$$, is the direction of the current induced in a conductor by changing magnetic field.

## Lenz's Law formula

$$\large{ \epsilon = -N \; \frac{ \partial \Phi_B }{ \partial t } }$$
Symbol English Metric
$$\large{ \epsilon }$$  (Greek symbol epsilon) = induced EMF $$\large{V}$$  $$\large{V}$$
$$\large{ \partial \Phi_B }$$ = change in magnetic flux $$\large{Wb}$$ $$\large{Wb}$$
$$\large{ \partial t }$$ = change in time $$\large{sec}$$ $$\large{s}$$
$$\large{ N }$$ = number of turns in coil $$\large{dimensionless}$$
