Basic law of electromagnetic induction which states that an induced voltage will have a polarity that opposes the current change that produced it. Faraday’s law of induction: makes use of the magnetic flux $Φ_{ B }$ through a hypothetical surface $Σ$ whose boundary is a wire loop. Since the wire loop may be moving, we write $Σ(t)$ for the surface. The magnetic flux is defined by a surface integral:

Since the wire loop may be moving, we write $Σ(t)$ for the surface. The magnetic flux is defined by a surface integral: 
\[Φ_{ B }=\iint _{ Σ(t) }^{ }{ B(r,t)\cdot dA } \]

\[Φ_{ B }=\iint _{ Σ(t) }^{ }{ B(r,t)\cdot dA } \]

\[Φ_{ B }=\iint _{ Σ(t) }^{ }{ B(r,t)\cdot dA } \]

\[Φ_{ B }=\iint _{ Σ(t) }^{ }{ B(r,t)\cdot dA } \]

\[Φ_{ B }=\iint _{ Σ(t) }^{ }{ B(r,t)\cdot dA } \]

where $dA$ is an element of surface area of the moving surface $Σ(t)$, $B$ is the magnetic field (also called “magnetic flux density”), and $B\cdot dA$ is a vector dot product (the infinitesimal amount of magnetic flux through the infinitesimal area element $dA$). In more visual terms, the magnetic flux through the wire loop is proportional to the number of magnetic flux lines that pass through the loop. When the flux changes – because $B$ changes, or because the wire loop is moved or deformed, or both—Faraday’s law of induction says that the wire loop acquires an EMF, $\varepsilon $, defined as the energy available from a unit charge that has travelled once around the wire loop. Equivalently, it is the voltage that would be measured by cutting the wire to create an open circuit, and attaching a voltmeter to the leads. Faraday’s law states that the EMF is also given by the rate of change of the magnetic flux:

For a tightly wound coil of wire, composed of $N$ identical turns, each with the same ${ \Phi }_{ B }$, Faraday’s law of induction states that:
