As the snow fell outside, the class moved to Electrical Phenomena . Alex felt like an engineer as he assembled his first circuit using a battery, a bulb, and a switch. He learned to use an Ammeter and a Voltmeter , realizing that current is like water flow while voltage is the pressure pushing it. He spent one afternoon proving Ohm's Law , adjusting a rheostat and watching the needle dance across the scale, confirming that as resistance goes up, the current fades.

Next came Electromagnetic Phenomena . Alex wound wire around an iron nail to create an electromagnet . He was amazed when a simple battery turned a piece of junk metal into a magnet strong enough to pick up paperclips. He then explored the magnetic field of a permanent magnet using iron filings, which mapped out invisible lines of force like a hidden fingerprint. Next came Electromagnetic Phenomena
