12.12 How to use flux time graphs to find emf time

Emf will be induced in a coil which is entering a magnetic field. When the coil is inside the magnetic field no emf is induced. When it leaves the magnetic field once again emf is induced but this time in the negtive direction. In this video I explain why using Faraday's and Lenz's law. I use a magnetic flux time graph and emf induced time graph to help explain.
