WebUse Faraday’s law with Lenz’s law to determine the induced emf in a coil and in a solenoid. The direction in which the induced emf drives current around a wire loop can be found through the negative sign. However, it is usually easier to determine this direction with Lenz’s law, named in honor of its discoverer, Heinrich Lenz (1804–1865). WebThis EMF, measured in volts, will also create a current flow. Faraday’s equation only tells us the magnitude of the EMF, not the polarity: ϵ = N dθ dt ϵ = N d θ d t. Where: ϵ ϵ = the electromotive force, in volts. N = the number of turns in a coil of wire. dθ d θ = the change in magnetic flux, in webers. dt d t = the time over which ...
