What is Faraday Ist law of electromagnetic induction?

Answer 1

Overall, induced voltage is proportional to the product of the number of loops of coiled wire and the rate at which the magnetic field changes

Answer 2

Faraday's laws of electrolysis relate the amount of liberated mass at an electrode to the quantity of electricity passing through the electrode. In an electrolytic cell, metal at an electrode's surface is dissolved into an electrolyte or deposited on an electrode by the application of electricity. Faraday's first law states that the amount of current passed through an electrode is directly proportional to the amount of material liberated from it. Faraday's second law states that the mass of two substances that are liberated from electrodes, given the same applied electrical charge, is proportional to the molecular weights of the two substances. An important industrial application of Faraday's law is electroplating, where a material is coated with a thin metallic layer to prevent corrosion or abrasion.

Answer 3

Faradays Law of Induction is 0= dEv/dr + DelxEv where Ev is the vector electric field and r= ct and dr=cdt thus 0= dEv/cdt + DelxEv= dBv/dt + DelxEv=0. B=E/c give the traditional formula. The elctromagnetic fields E and B are realted by c the speed of light. E=cB=zH=zcD, where z=375 Ohms, the free space impedance.

While this is the "recognized Faraday law, I think the proper Law is

0=dEv/dr + Del Er = dBv/dt + Del Er

my reason is that DelxEv is perpendicular to dEv/dr and thus could not sum to zero nby the laws of Mathematics.
