Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday’s law of induction. Lenz’s law describes the direction of the induced field.

Faraday’s Law of Induction and Lenz’s law. Faraday’s law of induction uses the ΦB-magnetic flux throughout an area of space surrounded by a wire loop. Here the flux can be described by a surface integral. magnetic flux. Where ‘dA’ is a surface element ‘Σ’.

Lenz’s law states that whenever there is a change in the magnetic flux through a conducting loop, a current arises to produce a magnetic field that balances the change, i.e. to keep ∫ A B ⃗ ⋅ n ⃗ int_A vec{B}cdot vec{n} ∫ A B ⋅ n constant. This is a result of Faraday’s law of induction. An externally applied magnetic field through an area induces a current.

Lenz’s law and Faraday’s law formula. Faraday’s law states that the voltage induced in a circuit is equal to the rate of change – that is, change in time – of the magnetic flux through a loop: EMF = dΦ / dt. Lenz’s law is the key second law that describes electromagnetic induction.

Through a series of experiments in 1831 Michael Faraday came to the. Two years later, Heinrich Lenz formulated Lenz's Law, which characterizes the direction.

Faraday’s and Lenz’s Law. Faraday’s experiments showed that the emf induced by a change in magnetic flux depends on only a few factors. First, emf is directly proportional to the change in flux Δ Φ. Δ Φ. size 12{ΔΦ} {} Second, emf is greatest when the change in time Δ t Δ t size 12{Δt} {} is smallest—that is, emf is inversely proportional to Δ t.

The minus in the Faraday’s law means that the EMF creates a current I and magnetic field B that oppose the change in flux Δthis is known as Lenz’ law. Faraday’s law of induction is the fundamental operating principle of transformers, inductors, and many types of electrical motors, generators, and solenoids.
