Their Applications An Engineers Simplified Model William A Stapleton PhD Ingram School of Engineering Texas State University San Marcos Models Scientists attempt to understand the way the world works . Unit 15. Today’s Concept:. . Ampere’s Law. Unit 15. , Slide . 1. Electricity & Magnetism Lecture 15, Slide . 2. We know for an infinite current carrying wire. Ampere’s Law. But what is . 2. Topic 24. Polarization. - linear. - circular. Electricity & Magnetism Lecture 24, Slide . 1. So far we have considered plane waves that look like this:. From now on just draw . E. and remember that . The Periodic Table. Everything in the world is made up of . elements. Invented by: . Dimitri. . Mendeleeve. There are a total of . 111 known elements. Periodic Table. On the periodic table located in the . Unit 8: Capacitors. Today’s Concept:. Capacitors in a circuits . Dielectrics. Energy in capacitors. Unit . 8, Slide . 1. Where we are…….. Unit 8, Slide . 2. C. V. Q. Q. This “. Q. ” really means that the battery has . What is magnetism?. Force of attraction or repulsion due to electron arrangement. Magnetic forces are the strongest at the poles. Magnets have two poles: North and South. Magnetic poles and fields. Magnets always have two poles. Often cheap relative to other geophysical techniques.. Can be measured with ground-based or airborne equipment.. Not usually very useful when looking at sedimentary structures. (We’ll see why later!). Magnetism day 1. What causes magnetism?. How is magnetism linked to electric charges?. Magnetic fields come from . moving. . charges. . a moving charge around an atom produces a magnetic field. currents in wires will produce magnetic fields. Chapter 13. Reminders 1. Lab this week due by Friday at 4:00 pm: . B3-CLE: . Coulomb’s Law of Electrostatics . Weekly Reflections #11 (due 11/04) and #12 (due 11/11) to be sent out later today.. Next week’s lab B1-WA: . simple electrical circuits – direct current DC. Alternating current (AC) vs direct current (DC). electric power distribution . household electricity. household wiring. Protection circuits - GFIC’s . SrIr. 1−x. Sn. x. O. 3. indicated this material was a Slater insulator. This is a rare insulator where the magnetism controls the conduction of electrons. The behavior can be controlled by altering the Sn content.. EQ: Which similarities can be used to classify substances on the basis of their conductivity and magnetic properties?. Agenda. Bell Ringer. PowerPoint with . Cornell . Notes. Gizmo Snippet . Brain Pop: Magnetism with Quiz. c. Investigate applications of magnetism and/or its relationship to the movement of electrical change as it relates to. Electromagnets. Simple . motors. Permanent . magnets. A. Magnetic . Forces. Magnetism from electricity. In 1820, Danish scientist . Hans . Christian . Oersted. discovered accidently that when electricity passed through a wire…a magnetic field was created. Which way would the compass needles point if we placed them around the wire?. material due to the arrangement of its atoms, particularly its electrons.. Lik. e poles will repel, opposite poles will attract.. Magnetic field lines describe the structure of magnetic fields in three dimensions..
