Question

Which expression incorporates Lenz's law into Faraday's law?

विकल्प

• \[\varepsilon=N\frac{d\Phi_B}{dt}\]

• \[\varepsilon=-\frac{dt}{d\Phi_B}\]

• \[\varepsilon=-N\frac{d\Phi_B}{dt}\]

• \[\varepsilon=-N\Phi_B\]

Answer 1

Faraday's law with Lenz's law incorporated is \[\varepsilon=-N\frac{d\Phi_B}{dt}\]. The negative sign captures the opposition to the change in magnetic flux.
