To determine whether an electromotive force (emf) is induced in a metallic loop placed in a non-uniform steady magnetic field, we can follow these steps: ### Step 1: Understand the Concept of Magnetic Flux Magnetic flux (Φ) through a surface is defined as the product of the magnetic field (B) and the area (A) through which it passes, taking into account the angle (θ) between the magnetic field lines and the normal to the surface. It is given by the formula: \[ \Phi = B \cdot A \cdot \cos(\theta) \] ...
