Faraday's Law: Quantifies the magnitude of the induced EMF. | Lenz's Law: Determines the direction of the induced EMF (and current).

Using magnetic fields to create voltage. A changing magnetic field induces a voltage (EMF) in a conductor. If the circuit is closed, this EMF drives a current.

The amount of magnetic field passing through a given area. Quantified by the formula: $\Phi_B = B * A * cos(\theta)$ where B is the magnetic field strength, A is the area, and θ is the angle between the magnetic field and the area vector.

The induced EMF in any closed circuit is equal to the negative of the time rate of change of the magnetic flux through the circuit: $\varepsilon = -N \frac{d\Phi_B}{dt}$ where N is the number of turns in the coil.

The direction of the induced EMF (and thus the induced current) will always oppose the change in magnetic flux that caused it.

Electromotive Force: The voltage generated by a changing magnetic field, which can drive a current in a closed circuit.

1. Determine the direction of the original magnetic field. 2. Determine if the magnetic flux is increasing or decreasing. 3. Determine the direction of the induced magnetic field (it opposes the change in flux). 4. Use the Right-Hand Rule to find the direction of the induced current from the induced magnetic field.

1. Changing the magnetic field strength (B). 2. Changing the area (A) of the loop. 3. Changing the angle (θ) between the field and the area.
