Production of electric field How does varying magnetic field produce an electric field?
Is it a natural phenomenon having no reason? i want the process/steps of producing of an electric field by a varying magnetic field.
 A: There isn't an answer to your question because a varying magnetic field doesn't really produce an electric field (and a varying electric field doesn't really produce a magnetic field). Time varying magnetic and electric fields are associated, but it is misleading to imagine that one causes the other.
Even physicists tend to instinctively think of electric and magnetic fields as separate things, but they aren't. Since Maxwell formulated his equations in 1862 we have known that they are both aspects of the electromagnetic field. An electromagnetic field can be separated into an electric part and a magnetic part, but this separation is observer dependant. By this I mean that different observers, e.g. observers moving at different velocities, will disagree about the relative magnitudes of the electric and magnetic fields. To get round this, these days we use an electromagnetic vector potential that includes both the electric and magnetic components. This potential is the same for all observers so its interpretation is unambiguous.
