Title: 2. OBTAIN YOUR OWN ELECTRICITY !!! JUST WITH A MAGNET
Course: THE MIST€RY OF ELECTRICITY.I > Section: 2. ELECTRICITY MYSTERY II

As you already know electricity is a physical phenomena associated with the presence and flow of electric charge. But, how can we get it?

The most used form for generating electricity is based on Faraday’s law, and it is called ELECTROMAGNETIC INDUCTION. It can be experimented by simply rotating a magnet within closed loops of a conducting material (e.g. copper wire). But leave the video 2 explains that:

Electromagnetic induction was discovered independently by Michael Faraday and Joseph Henry in 1831; however, Faraday was the first to publish the results of his experiments. In Faraday's first experimental demonstration of electromagnetic induction (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or "torus”. Based on his assessment of recently discovered properties of electromagnets, he expected that when current started to flow in one wire, a sort of wave would travel through the ring and cause some electrical effect on the opposite side. He plugged one wire into a galvanometer, and watched it when he connected the other wire to a battery. Indeed, he saw a transient current (which he called a "wave of electricity") when he connected the wire to the battery, and another when he disconnected it. This induction was due to the change in magnetic flux that occurred when the battery was connected and disconnected. Within two months, Faraday had found several other manifestations of electromagnetic induction. For example, he saw transient currents when he quickly slid a bar magnet in and out of a coil of wires, and he generated a steady (DC) current by rotating a copper disk near the bar magnet with a sliding electrical lead.

Faraday's experiment try to induce a current from a magnetic field, with a battery on the left, an iron ring in the centre, and a galvanometer on the right.

Change in the magnetic flux of the left coil induces a current in the right coil.
