Sanika: The Orlando Science Center is known for using fun tricks and crafts to teach kids about different parts of science, and this time Alex Arech is joining the fun. SHELDON: — JASON: He’s at the Science Center participating in a magnet race that helps him understand how power plants work. >> There are magnets and tubes. >> WE ARE TALKING ABOUT CURRENTS, SO DO MAC IT — MAGNET RACE. Here is a magnet he has one and attaches to three. Drop these from the top of the tube to the bottom to show how I am an Agnes Magnet Racer. This is the fastest magnet racer. >>These are hollow. >> 3, 1, 2, 3. I will go again. on three. >> Done. >> We are switching sides. >> It’s not a magnet. >>I will win this time. I’m one — win. – won. >> what happened. >> If you try to stick a method on this tube they are not magnetic so how does this work? This has to do with what we call eddy currents . The tube is interacting with the electrons next to the copper tube, so when the metric drops, it pushes the electrons around to form an outbreak, creating an electromagnetic field that slows down the method. You try to push the method aside, you try to push it through, and it slows down just like that, and you’re the loser in today’s magnet race, and we ignore the previous race. >> I’m sure you can do other things with packets. — Magnet >> This same principle is how we build power plants. That’s when the copper wire has a magnet that moves back and forth on the copper wire, pushing electrons and generating electricity. >> Here’s another experiment. We threw the tube away. >> We were creating the current itself, but here we do something similar, but instead of a magnet passing through the tube, we create it by expending its will. – Wheel. We are charging the capacitors that power the electromagnetics — the electromagnetics that charge these rings. I think we were all charged the way we wanted. >> We have nice rates. >> Load it up and see who wins. >> Instead of charging with copper, we are charging and monitoring metal tubes. >> We make our own electromagnets. >> If anyone wants to see this, please do so. >> You can go to our center Go to our website with more scheduled activities through our building. >> Thank you for joining us for Science in IT.Jason: If you want to see what other cool stuff is going on
