Electromagnetic Induction
This interactive simulator explores Electromagnetic Induction in Electricity & Magnetism. Move magnet through coil. Faraday's law visualized. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: For learners comfortable with heavier math or second-level detail. Typical context: Electricity & Magnetism.

How it works
Moving a magnet changes magnetic flux Φ through a coil. Faraday’s law gives induced emf ε = −dΦ/dt (here Φ includes N turns). Ohm’s law gives I = ε/R. Lenz’s rule is reflected in the sign: the induced current creates a field that opposes the change in flux.
