Description
This animated visual effect demonstrates the principle of electromagnetism. An electrical circuit, consisting of a battery, resistor, and a switch connected to a wire loop, is shown. As the switch is closed, a glowing current flows through the circuit. Simultaneously, iron filings scattered on a white surface around the wire loop visibly align to form concentric circles, illustrating the magnetic field generated by the electric current. This clear and precise visualization is ideal for educational content, scientific presentations, and explainer videos that require a compelling demonstration of physics concepts.
