Opposites attract. Electric Field. A region around a charged object in which an electric force is exerted on another charged object.. 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!). 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.
