==Key Stage 5==
===Meaning===
'''Faraday's law of [[Electromagnetic Induction|electromagnetic induction]]''' states that the [[Electromagnetic Induction|induced]] [[emf]] in a circuit is equal to the rate of change of [[Magnetic Flux Linkage|magnetic flux linkage]] through the circuit.
===About Faraday's Law of Electromagnetic Induction===
*The [[Electromagnetic Induction|induced]] [[emf]] opposes the change in [[Magnetic Flux|magnetic flux]].
*[[Magnetic Flux Linkage|Magnetic flux linkage]] is defined as the product of the number of turns in the coil and the [[Magnetic Flux|magnetic flux]] through the coil.
*'''Faraday's Law''' is fundamental in the operation of [[generator]]s, [[transformer]]s, and various electromagnetic devices.
===Formulae===
'''Faraday's Law''' is stated mathematically as:
*<math>\varepsilon=-\frac{\Delta\Phi}{\Delta t}</math>
Where,
*<math>\varepsilon</math> is the [[Electromotive Force|electromotive force]]
*Φ is the magnetic flux
*t is the time.
The negative sign in the equation represents [[Lenz's Law]], indicating that the [[Electromagnetic Induction|induced]] [[emf]] opposes the change in [[magnetic flux]].
Additionally Φ is given by:
*Φ=𝐵𝐴cos𝜃
Where:
*𝐵 is the magnetic field strength
*𝐴 is the area of the coil
*𝜃 is the angle between the field and the normal of the area
