The magnetic flux Φ through a circuit has to be considered carefully in the application of Faraday's law given in equation ().For example, if a circuit consists of a coil with five closely spaced turns and if ϕ is the magnetic flux through a single turn, then the value of Φ for the five-turn circuit that must be used in Faraday's law is Φ = 5ϕ.

Permeability (electromagnetism)

In electromagnetism, permeability is the measure of the resistance of a material against the formation of a magnetic field, otherwise known as distributed inductance in transmission line theory.Hence, it is the degree of magnetization that a material obtains in response to an applied magnetic field. Magnetic permeability is typically represented by the (italicized) Greek letter μ.

Electric circuit analogies

Water flowing in a pipe 'The water circuit' In this well-known analogy a battery is seen as a pump and resistances as constrictions in a pipe. The pipes form a circuit and are already full of water. A more powerful pump means a higher voltage battery. This nicely shows that a big voltage causes a big current.
