What does Faraday's Law of electromagnetic induction say?
Electromagnetic induction underlies the operation of generators, all electric motors, transformers, induction motors, synchronous motors, solenoids, and most other electrical machines. Faraday’s law of electromagnetic induction states that:
When was the concept of electromagnetic induction discovered?
The concept of electromagnetic induction was discovered simultaneously in 1831 by Faraday in London and Joseph Henry, an American scientist working in New York that same year. Faraday’s law describes electromagnetic induction, whereby an electric field is induced, or generated by a changing magnetic field..
Which is an example of an induced current?
Induced current: ε=vBLLength of rod and velocity perpendicular to B. - The emf associated with the moving rod is equivalent to that of a battery with positive terminal at a and negative at b. Motional emf: general form (alternative expression of Faraday’s law)
How is EMF induced in an electric circuit?
The emf induced in an electric circuit always acts in such a direction that the current it drives around. Consider the case in Figure 3 of a closed rectangular loop of wire in the xy-plane translated in the x-direction at velocity v. Thus, the center of the loop at xC satisfies v = dxC / dt.
