Electromagnetic induction is found by Lorentz and Faraday

Lorentz's electromagnetic induction

V={\frac {dB}{dt}}

Faraday's electromagnetic induction

-\epsilon =-{\frac {d\phi }{dt}}

Circular loop		$B=Li={\frac {\mu }{2r}}i$ $V={\frac {d}{dt}}B=L{\frac {di}{dt}}$
Coil of N circular loops		$B=Li={\frac {N\mu }{l}}i$ $V={\frac {d}{dt}}B=L{\frac {di}{dt}}$ $\phi =-NB=-NLi$ $-\epsilon =-{\frac {d\phi }{dt}}=-L{\frac {dB}{dt}}=-NL{\frac {di}{dt}}$
