Electromagnet Simulations

Select a device to explore how an electric current creates a magnetic field and produces movement.

Electromagnetic Door Lock

Use an electromagnet to move a locking bolt and control a door lock.

Open simulation

Motion-Activated Shower

Explore how a sensor and electromagnet control the flow of water.

Open simulation

Electromagnetic Water Gate

See how a float switch activates an electromagnet to open and close a water gate.

Open simulation

Electromagnetic Marble Run

Release a marble by using an electromagnet to pull a gate pin.

About this simulation

These four device simulations show how an electric current can create a magnetic field and produce movement in a practical system. Students can examine a door lock, shower valve, water gate and marble-run mechanism, then identify the electrical input, electromagnet, moving component and resulting action. The collection is designed for secondary science lessons on electromagnets, energy conversion and simple control systems.

Key concepts: Electromagnets, Electric current, Magnetic fields, Forces and motion.
