Mutual Inductance
This interactive simulator explores Mutual Inductance in Electricity & Magnetism. Coupled L₁, L₂ with k and M; sinusoidal primary drives secondary current through R₂. 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
Two magnetically linked inductors satisfy **L₁ di₁/dt + M di₂/dt = V − R₁i₁** and **M di₁/dt + L₂ di₂/dt = −R₂i₂** for a simple secondary loop. The **coupling coefficient** **k** sets **M = k√(L₁L₂)**. Changing **k** or **ω** changes how much current is induced in the secondary — a compact alternative to the ideal-turns **Transformer** page.
