PPT-Electromagnetism

Objectives SPI 0807121 Recognize that electricity can be produced using a magnet and wire coil SPI 0807122 Describe the basic principles of an electromagnet SPI 0807123 Distinguish among the Earths magnetic field a magnet and the fields that surround a magnet and an electromagnet. 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 1 Electric and 64257elds 1 111 Electrostatic Force 1 112 Uniform electric 64257elds Knowing about the properties of electromagnets is a crucial underpinning for understanding how magnetic 57374elds are generated in nature in the surface of the Sun and in the interior of Earth In preparation for this activity or as a followup please 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!.
