PPT-Electromagnetism

Have you ever heard of electromagnetism If so what is it If not what do you think it is Bellringer Take a stroll down science history lane to investigate the discovery of one of my personal favorite areas of physics. PHYSICAL LAW We are told that our present understanding of physical law was ushered in by the Quantum Revolution which began around 1900 and was brought to fruition around 1930 with the formulation of modern Quantum Mechanics The photon was supposed Electric Current and Magnetism. In 1819, Hans Christian . Oersted. , a Danish physicist and chemist, and a professor, placed a compass needle near a wire through which he could make electric current flow. . By: Stephon Lemay & Luz Ruiz. What Is It???. . Electromagnetism is defined as the force between electrically charged particles.. Electromagnetic induction. Electromagnetic induction is creating an electric current from a changing magnetic . Corinne . Manogue. and the whole Paradigms Team. physics.oregonstate.edu/paradigms. Philosophy of the Paradigms. Our approach teaches physics as physicists think about it, namely in terms of concepts that broadly underlie the various subfields: energy, symmetry, wave motion, rotations and so forth. . Vector.
