To solve the problem of ranking the regions of the graph according to the magnitude of the induced EMF in the loop, we can follow these steps: ### Step 1: Understand the Relationship Between Magnetic Field and Induced EMF The induced EMF (ε) in a closed loop is given by Faraday's law of electromagnetic induction, which states: \[ \varepsilon = -\frac{d\Phi_B}{dt} \] where \(\Phi_B\) is the magnetic flux. For a uniform magnetic field passing normally through the loop, the magnetic flux is given by: ...
