Nyquist Plot (linear systems)
This interactive simulator explores Nyquist Plot (linear systems) in Electricity & Magnetism. Open-loop L(jω) in the complex plane vs frequency; critical point −1 and distance teaching aid. 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: Best once you already know the basic definitions and want to build intuition. Typical context: Electricity & Magnetism.

How it works
Polar plot of the open-loop frequency response L(jω). Compare with the Bode diagram of the same transfer function: magnitude and phase become radius and angle here. The critical point −1 marks where unit gain meets −180° phase.
Key equations
LP1: L = 1/(1 + jωτ)
HP1: L = jωτ/(1 + jωτ)
Integrator: L = K/(jω)
2nd LP: L = ωₙ² / ((jω)² + 2ζωₙ(jω) + ωₙ²)
