Faraday’s Law of Induction explains how an electric current produces a magnetic field and also, how a changing magnetic field generates an electric current in a conductor.
While Faraday's law explains how magnitude of the EMF is produced, Lenz's law explains the direction that current will flow. The lenz's law states that the direction is always in a way which it will oppose the change in flux which produced it. Lenz's law simply explains that any magnetic field produced by an induced current will be in the opposite direction to the change in the original field.
In this lab, they are clearly making use of Faraday's law because they are inducing a current due to changes in magnetic flux. This situation involves Faraday's law because in Faraday's law, the induced magnetic field inside a loop will always move to keep the magnetic flux in the loop constant.
V (speed) = F (frequency) x Wavelength If we rearrange the formula, making frequency the subject; F (frequency) = Speed ÷ Wavelength F = 300,000 m\s x 4.5 e -10m F = 0.08810409956 Hz
