Transcript of transformers
The principle behind the operation of a transformer, electromagnetic induction, was discovered independently by Michael Faraday and Joseph Henry in 1831. However, Faraday was the first to publish the results of his experiments and thus receive credit for the discovery. The relationship between emf and magnetic flux is an equation now known as Faraday's law of induction:
where is the magnitude of the emf in volts and ΦB is the magnetic flux through the circuit in webers. Laura Carolina Carmona Giraldo
