Quit is based on the current- carrying conducter tes magnetic field around it. 90. For the diagram below: a) Name the parts of the motor that are labeled. c ) b) Determine which end of the coil is N. State in which direction the coil will spin. D C S N B 91. What is Faraday's principle? Oersted's discovery? Lenz's law? 92. A transformer consists of a primary coil of 100 turns and a secondary coil of 5000 turns. The primary potential difference and current are 120 V and 2.00 A. What is the secondary potential difference? What is the secondary current? What kind of transformer is it and why
