## Explanation

The turning loop generates a change in magnetic flux through the area enclosed by the loop, which according to **Faraday's Law of Electromagnetic Induction**, induces an emf. This is mathematically represented as:

Where $\mathcal{E}$ is the electromotive force (emf) and $\Phi_B$ denotes the magnetic flux.

If the number of turns in the wire loop is $N$, the induced emf becomes:

$\mathcal{E} = -N \frac{d\Phi_B}{dt}$This can also be viewed in the context of **motional emf**, which occurs if part of a circuit moves through a magnetic field. The magnitude of the motional emf can be described by:

Where $B$ is the magnetic field strength, $l$ is the length of the wire in the magnetic field, $v$ is the velocity of the wire, and $\theta$ is the angle between the velocity and the magnetic field direction.

The continuous rotation of the loop results in a **periodic change in the magnetic flux** and thus generates an **alternating current (AC)** if the loop is part of a complete circuit. This forms the basis of many electric generators and induction motors.
