Faraday's law of induction states that the EMF induced by a change in magnetic flux is EMF=−NΔΦΔt EMF = − N Δ Φ Δ t , when flux changes by Δ in a time Δt.
Faraday's Laws of Electromagnetic Induction consists of two laws. The first law describes the induction of emf in a conductor and the second law quantifies the emf produced in the conductor.
The magnitude of the electromotive force is proportional to the rate of change of the field. Faraday's third law of electromagnetic induction. The sense of the induced electromotive force depends on the direction of the rate of the change of the field.
An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the magnetic field B.
In the order presented, the equations are called: Gauss's law, the no-monopole law, Faraday's law and the Ampère–Maxwell law. It would be a real advantage to remember them.
SI unit:- volts
It is abbreviated E in the international metric system but also, popularly, as emf. Despite its name, electromotive force is not actually a force. It is commonly measured in units of volts, equivalent in the metre–kilogram–second system to one joule per coulomb of electric charge.
The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the circuit.
i. e = E/Q.
ii. Difference between EMF and Potential Difference
