⚡ Faraday's Law of Electromagnetic Induction

📚 Understanding Faraday's Law

Electromagnetic Induction: When a conductor moves through a magnetic field (or when the magnetic field through a conductor changes), an electromotive force (EMF) is induced in the conductor.

The Simulation: This shows a coil rotating in a uniform magnetic field. As it rotates, the magnetic flux through the coil changes, inducing an EMF according to Faraday's Law.

Key Concepts:

• Magnetic Flux (Φ) = B × A × cos(θ) - depends on the angle between field and coil area
• Maximum EMF occurs when the flux is changing most rapidly (θ = 90° or 270°)
• The negative sign (Lenz's Law) indicates the induced EMF opposes the change in flux
• More turns (N) or faster rotation (ω) produces higher induced voltage
