WebFaraday’s law of electromagnetic induction, also known as Faraday’s law, is the basic law of electromagnetism which helps us predict how a magnetic field would interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction. WebAn electric current is a flow of charged particles. In metal conductors the charged particles are free electrons. The electrons are free to move from one ion to another and a net flow of these...
WebThe electromotive force (e.m.f) is defined as: The amount of chemical energy converted to electrical energy per coulomb of charge (C) when passing through a power supply This can also be written as: E.m.f can be represented by the symbol ε (greek letter epsilon) It is not actually a force, and is measured in volts (V)
