What is the difference between Faraday's Law and Lenz's Law?

Faraday's Law: Quantifies the induced EMF. | Lenz's Law: Determines the direction of the induced EMF (opposes change in flux).

Compare voltage step-up and step-down transformers.

Step-Up: More loops on the secondary side. | Step-Down: More loops on the primary side.

Define Electromagnetic Induction.

Generating a voltage using magnetic fields. If this voltage is in a complete circuit, it creates a current.

What is Magnetic Flux?

A measure of the amount of magnetic field lines passing through a given area, calculated as ΦB=BdAΦ_B = ∫ \overrightarrow{B} ⋅ d\overrightarrow{A}.

Define Faraday's Law.

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: ε=NdΦBdtε = -N \frac{dΦ_B}{dt}.

What is Lenz's Law?

The induced EMF always opposes the change in magnetic flux that caused it.

Define Motional EMF.

EMF generated by moving an object (like a conducting rod) in a magnetic field. ε=Blvε = Blv

What is a Weber (Wb)?

The SI unit of magnetic flux, equivalent to Tm².

What are the differences between Faraday's Law and Lenz's Law?

Faraday's Law: Quantifies the induced EMF based on the rate of change of magnetic flux. | Lenz's Law: Determines the direction of the induced EMF, opposing the change in flux.

Compare voltage step-up and step-down in transformers.

Step-Up: More loops on the secondary side, increases voltage. | Step-Down: More loops on the primary side, decreases voltage.
