Lenz's law

REA Catalogado

Average rating:

A very interesting animation of Faraday´s Magnetic Induction and Lenz´s Laws. A circular metallic ring is located in a region with an uniform external magnetic field. First, the ring is located in a plane perpendicular to the external field lines and the intensity of the field is increased, so the induced current on the ring and its corresponding field lines are shown. Then the ring is rotated and the corresponding induced currenta and field lines are presented.

This video and animation illustrate Faraday's Law. As a permanent magnet is moved back and forth in the vacinity of a coil of conducting wire, a current is induced in the coil (as measured by the ammeter in the video). This induced current is proportional to the rate of change of magnetic flux through the enclosed area of the coil, and flows in such a direction as to generate a field whose change in flux opposes that change. In the animation, we show the evolution of the magnetic field during this process.

My Hero: Law of Love

RE Sugerido

Un film que demuestra que en el mundo todos los niños necesitan de un amigo/a. Podemos apreciar niños de India y Pakistán mandándose cartas como una forma de comunicarse. Esta gran labor la ha tomado una asociación llamada Friends Without Borders. En este corto apreciamos que aun las personas más pequeñitas del mundo pueden romper la barrera de rivalidad para intercambiar señales de amor.

Promedio: 3 (1 reseña)

On Wednesday, February 1 Dr. Steven Jones gave the following presentation on 9/11 and the physics of falling bodies and how it was physically impossible for these structures to have collapsed based on the conclusion that our government has given us. This video could possibly be the most conclusive work yet in disproving the 9/11 myth. Utah Valley State College

Limit laws

RE Sugerido

In this video, we show how to define and calculate limits of function values. The calculations rules are straighforward, and most of the limits we we need can be found by substitution, graphical investigation, numerical aproximation, algebra, of some combination of these.

Moderator William Uricchio sets the scene for panelists’ discussion of current copyright wars with a brief historical overview of copyright protection. In 1790, when news traveled by horse and carriage, copyright protection was good for 14 years. Today, when a digital, networked society enables instant transmission of data, protection lasts 70-plus years. Uricchio notes, “Bizarrely, the faster information circulates, the longer we’re extending copyright protection. It seems totally at odds with where our constitution framers and case law emerged from.”
