Faraday's Law is an important idea in science. It tells us that when the magnetic field around a wire changes, it creates an electric force called electromotive force (EMF).

We can write it like this:

$\text{EMF} = -\frac{d\Phi_B}{dt}$

Here, $\Phi_B$ stands for the magnetic field changing. The negative sign shows which way the EMF is going. This idea also connects to Lenz's Law, which explains why the EMF acts the way it does.

Knowing about Faraday's Law is very important for something called electromagnetic induction. This means that we can make electric currents just by changing magnetic fields.

Examples of Faraday's Law:

• Electric Generators: When we turn coils in a magnetic field, they produce electricity.
• Transformers: If the current in one coil changes, it can create a voltage in another coil nearby.

This basic idea is really important in today's world. It helps us with everything from making power to running our favorite electronic gadgets.
