Nikola Tesla

0:03 Calarogu Shark Media. Hi, I'm Mark Ellison and today's theme is Nicola Tesla's birthday. Brilliant inventors electricity and the scientists who shaped modern life. Question one, in honor of Nicola Tesla. What SI derived unit? Measures magnetic flux density the strength of a magnetic field, and is commonly used to specify fields in MRI scanners and particle accelerators. Question two. At the eighteen ninety three World's Columbian Exposition in Chicago, which electrical power system illuminated the fairgrounds, helping to settle the war of the currents between Edison's DC and Westinghouse Tesla's approach.

0:52 Question three, which largely self taught English scientists discovered electromagnetic induction in eighteen thirty one, laid the foundations of electric motors and transformers, and lends his name to the SI unit of capacitance. Question four, whose eighteen sixties equations unified electricity and magnetism and revealed that light is an electromagnetic wave, providing the theoretical groundwork for radio and much of modern physics. Question five, in eighteen ninety eight at Madison Square Garden, what device did Nikola Tesla publicly demonstrate steered by invisible radio signals that he called a tele automaton, and that foreshadowed wireless control and robotics. We'll be right back with these answers after this break. Welcome back. Question one, what SI unit named for Niklotesla measures magnetic flux density? Answer the Tesla t D, adopted by the International System in nineteen sixty one. Tesla equals one weber per square meter.

2:06 Naming the unit recognizes Tesla's pioneering work in electromagnetism and high field devices. Question two which system lit the eighteen ninety three Chicago World's Fare AC or DC? Answer? Alternating current AC. Westinghouse used Tesla's polyphase AC system to power the Fare, showcasing AC's efficiency for long distance transmission. The success paved the way for projects like the Niagara Falls Hydroelectric Plant. Question three. Who discovered electromagnetic induction and lends his name to the Farrad Answer? Michael Faraday. Faraday showed that a changing magnetic field can induce an electric current underpinning generators and transformers. The Farad honors his profound impact on electrical science. Question four, who unified electricity and magnetism with equations in the eighteen sixties. Answer James Clerk Maxwell.

2:58 Maxwell's equations predict a electromagnetic waves traveling at the speed of light. Later experiments by Hertz confirmed them, leading to technologies from radio to Wi Fi. Question five. What radio controlled invention did Tesla demo in eighteen ninety eight? Answer a radio controlled boat teleautomaton. Tesla patented a method for remotely controlling vehicles by radio that year and amazed crowds by maneuvering a model boat without wires. The concept anticipated modern remote control and robotics. That concludes today's five daily Trivia questions. I'm Mark Ellison, and today's questions were crafted with the help of AI technology. See you tomorrow.
