Electric Motor/Generator: this inexpensive and common motor can also serve as a generator of AC electricity- here lightning an LED when the shaft of the rotor is spun by hand. Most electrical energy we use today is produced by moving a magnet near a coil of wire (known as Faraday’s law of induction) to produce an electric current. Removing the permanent magnet casing reveals this design to use 9 separate copper windings. I made a transparent second rotor with six neodymium magnets- and when thes

Electric Motor Build: One of the most important inventions consists of only three basic components as shown here: coil, magnet, and a battery with lead wire posts. The wire of the spinning coil has an insulating coating on it- and this coating is carefully scrapped off one side of the thin wire on each end. When current passes through the coil it becomes an electromagnet and the permanent magnet repels it making it spin- as it turns the current goes on and off depending on if the copper wire pos

fut.cristiano on Instagram: "The Tesla Cybertruck is a battery electric pickup truck built by Tesla, Inc. since 2023.[6] Introduced as a concept vehicle in November 2019, it has a body design reminiscent of low-polygon modelling, consisting of flat stainless steel sheet panels. Tesla initially planned to produce the vehicle in late 2021, but after many delays, it entered production in mid 2023 and was first delivered to customers in November. Three models are offered: a tri-motor all-wheel drive
