Logic, not magnetics
The model treats the coil as a digital input. Real coils have inductance and need proper suppression.

Relay Simulator
Energise a relay coil and observe the contacts change state.

Teaching model. This simulation uses ideal elements and a deterministic solver. It does not represent real transient behaviour, heating, tolerances or fault energy. Do not use it as a design or safety calculation.
