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. A unit of measure of . magnetic field strength. , the _____________, is named after him.. connected. oersted. Electricity and Magnetism. How can an electric charge create a magnetic field?. . How is an electromagnet controlled?. 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 . 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!). Magnets. permanent magnets. e. lectromagnets. t. he Earth’s magnetic field. magnetic forces. applications. Magnetism. 2. Magnetism. two sources of magnetism. permanent magnets. Electromagnets . (currents in wires). Static electricity. Why do I get a shock when I walk across the rug and touch the door knob?. Why do socks stick to my shirts in the dryer?. Why does my hair stick to my comb?. What is lightning?. What produces the aurora?. 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..
