9. Accelerated Charges Radiating Electromagnetic Waves

View the complete OCW resource: http://ocw.mit.edu/resources/res-8-00... Instructor: Wit Busza General discussion of electromagnetic fields produced by moving charges, in particular by charges that accelerate. NOTE: These videos were originally produced as part of a physics course that is no longer available on OCW. Chapters 0:00:00 Title slate 0:00:21 Problem: what is the electric field at a given point in space from a charged particle? 0:04:05 A charge oscillates with Simple Harmonic Motion (SHM) along the z-axis. The radiated field is calculated along the z-axis. 0:07:15 The field is calculated along a line which subtends 30 degrees with the z-axis. 0:07:39 The field is calculated along the y-axis. 0:08:42 A charge is moving in a circle with constant speed. The resultant radiated electromagnetic field is calculated. 0:12:58 The total power radiated by a charge moving with SHM along a straight line is calculated.
