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. 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. simple electrical circuits – direct current DC. Alternating current (AC) vs direct current (DC). electric power distribution . household electricity. household wiring. Protection circuits - GFIC’s . 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: . 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.

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?. An object that does NOT conduct electricity…. insulator. The measure of how much a material opposes the flow of current…. resistance. A circuit that has only one path that electricity can follow…. 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.. Today’s Concept:. Conductors. . Capacitance. Electricity & Magnetism Lecture 7, Slide . 1. THERE ARE ONLY THREE THINGS YOU NEED TO KNOW TO DO ALL OF HOMEWORK. 1. . . E. . =. 0 . within the material of a conductor:. Magnets. permanent magnets. e. lectromagnets. t. he Earth’s magnetic field. magnetic forces. applications. Magnetism. 2. Magnetism. two sources of magnetism. permanent magnets. Electromagnets .
