EM induction finally explained in simple terms! This second episode details the basic principle of EM induction: How to generate electricity by moving a conductor in a magnetic field. Watch this video: if suddenly you were moved back in time thousands of years ago, you would know how to produce electricity: Take a piece of metal, move it around a magnet the right way and you’ve got yourself a battery! The video explains what happens within the metallic bar when you move it in a magnetic field, and how this results in an emf across the bar. Then an example is shown where a bar is sliding on metallic rails, which are themselves connected to a load (Resistance or lamp bulb). This set up is an electric circuit where the battery is the moving bar! We prove that the mechanical energy provided to move the bar is equal to the electrical energy dissipated in the load (Conservation of energy). In the first episode: https://youtu.be/N44pn9rYtbE, we gave a basic example of application of EM induction (The dynamo in a lamp), as well as the three basic principles to be understood in order to study EM induction in good conditions _ The effect of a magnetic field on a moving charge (F= qvB), _ The effect of an electric field on a charge located between two charged plates (F=qE), _ The effect of a magnetic field on a wire carrying an electric current (F=ILB). This course is based on the IB Physics HL program. If you enjoy this video and find it useful for your studies, please like the video and subscribe to the channel!

This video is aimed at IB (SL or HL) or A-Level students preparing for their exams . It presents an exercise based on a past exam, and that deals with energy, power and energy production, more specifically hydroelectric energy production (IB: Chap 8, A-Level: topic Energy and Power). Watch the video and when the questions appear, pause it, try to figure out the answer by yourself, then come back and resume the video. - - - - - - - This video is produced and presented by Edouard Reny, Ph.D. in materials sciences and private tutor in Physics. http://www.physics-tutor.nl/ If you enjoy these videos and / or find them useful for your studies, please like and subscribe!

Feynman diagrams are a graphical representation of the processes involved in particle physics reactions. This video is the third episode of a series of three that presents what are Feynman diagrams, how to understand and use them, and how to build them. In this episode, you will learn how to build your own diagram using conservation laws and rules about forces to decide the various steps that could occur during a particle physics reaction. Learning by example is often the best way: in this video, we will build many Feynman diagrams together. These will be based on particle physics reactions like muon decay, pion decay, Kaon decay etc. Some of these examples are under the form of exercises, so you can train your new skills! Of course, corrections are provided on the white the board. Feynman diagrams are an insightful tool that puts to light the wonders of particle physics. The reactions occurring in particle physics are a marvel of processes involving the forces of nature (weak force, strong force and electromagnetic force). Writing these like a chemical reaction does not provide information about the processes involved, just what you start up with, and what you end up with. One can use the Quantum Chromodynamics (QCD) and Quantum Electrodynamics (EOD) to model quite well what is going on, but the mathematics involved is not for everyone! Instead, graphical representation of these reaction, invented by Richard Feynman, allow all to easily visualize the processes involved: Feynman diagrams. He introduced these originally as a graphical aid for visualizing and calculating interactions between electrons and photons. Today, Feynman diagrams are commonly used to depict all types of particle interactions. These videos are intended to help high school students with their physics studies as well as high school physics teachers wondering how to approach the topic with their students. **** Access to the Videos **** Introduction: Content review of the Feynman Diagram mini-series https://youtu.be/O9ihGuK53Ww Episode 1: What is a Feynman Diagram?

A systematic technique to solve kinematics (motion) problems with constant acceleration. With enough training, you can solve the easiest questions in just a minute, and most others in 2 or 3! You have 4 friends to help you with that: The motion equations. This video will show you how to tame them, and put them at your service. So now, no more cold sweats when you encounter motion questions with displacement, velocity, acceleration! If you wish to go more in depth and at a slower pace, enroll in the course "Gravity, The Basics". The first section is a detailed review of the the technique on how to solve linear motion problems. https://www.udemy.com/course/gravity-the-basics/?referralCode=91F294FF9D2454F6CEE5 - - - - - - - - - - - - This video is produced and presented by Edouard Reny, Ph.D. in materials sciences and private tutor in Physics.
