Additional Study Resources
Use the supplemental resources below to support your post-lecture study.
YouTube Videos
Pre-Med Academy's video series on magnetism. These three videos cover Faraday's Law, Lenz's Law and the Lorentz Force. In the Faraday's Law video, the presenter uses calculus notion for the law, just remember that for us, $d\phi_B/dt = \Delta \phi_B/\Delta t$

Simulations
From the PhET discription "Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!"

Demos
Check out the crazy ways copper will react to strong magnets and the effects of induction.
