Physics with Calculus
It is the limit of NΔΦΔt\(\displaystyle\) N\(\frac{\Delta\Phi}{\Delta t}\) as Δt\(\Delta\) t approaches zero
It is equal to the magnetic flux itself at any time
It is found by adding the flux values at the beginning and end of the interval
It is the value of NΔΦN \(\Delta\)\(\Phi\) multiplied by Δt\(\Delta\) t for large intervals
