To determine the effect of doubling the number of loops of wire in a coil on the induced emf, we can refer to Faraday's Law of Electromagnetic Induction. Faraday's Law states that the induced emf (ε) in a coil is directly proportional to the rate of change of magnetic flux (Φ) through the coil and the number of loops (N) in the coil. Mathematically, it is expressed as:

$$ \varepsilon = -N \frac{d\Phi}{dt} $$

Where:
- $\varepsilon$ is the induced emf,
- $N$ is the number of loops,
- $\frac{d\Phi}{dt}$ is the rate of change of magnetic flux.

If the number of loops $N$ is doubled, the new number of loops becomes $2N$. Substituting this into the equation, we get:

$$ \varepsilon' = -(2N) \frac{d\Phi}{dt} $$

This shows
