Faraday/Neumann Law of ElectroMagneticInduction 

We are trying to show that 

It is clear that 

Now, ΔV/Δt is
represented by the slope
of the triangular trace on the
oscilloscope. 
If we maintain a constant amplitude for this varying
voltage then we can state that this slope is directly
proportional to the frequency of the supply. 

Therefore, if a graph of induced emf against
frequency of the supply is a straight line passing
through the origin, then we will have verified the
Faraday/Neumann
law
