Suppose we have a closed circuit with a time-varying magnetic flux. An EMF is inducted on the circuit.

Where would we put the battery representing the EMF? For example, suppose we have a resistance in the circuit and we want to know the intensity through it. Would we just set the voltage against its extremes to be equal to the EMF?

If so, would we, in the general case where there are more elements, analyze each one as if there was a voltage between its extremes?

If you want to know just current throught the loop, break the loop at any small segment of it and connect the "battery" of the same EMF there.
That would work.

## 1. Where is the EMF located in a circuit under induction?

The EMF (electromotive force) is located in the coil of wire in a circuit under induction. This is because the changing magnetic field created by the current flowing through the coil induces an EMF in the same coil.

## 2. Is the EMF located in the battery or power source?

No, the EMF is not located in the battery or power source in a circuit under induction. The battery or power source provides the initial energy to create the current, but the EMF is only induced in the coil of wire when there is a changing magnetic field.

## 3. Can the EMF be located in more than one place in a circuit under induction?

Yes, the EMF can be located in more than one place in a circuit under induction. This is because the changing magnetic field can induce an EMF in multiple coils of wire, depending on the design of the circuit.

## 4. How is the location of the EMF determined in a circuit under induction?

The location of the EMF in a circuit under induction is determined by the location of the coil of wire. The changing magnetic field must pass through the coil in order to induce an EMF in it.

## 5. Does the location of the EMF affect the strength of the induced current?

Yes, the location of the EMF can affect the strength of the induced current in a circuit under induction. The closer the coil of wire is to the changing magnetic field, the stronger the induced EMF and current will be.
