- The circuit was in DC steady state for t < 0. A quantity absolutely cannot change suddenly in this circuit, and in general unless nothing else can happen. It must be continuous across the switch opening. Which is that quantity? (The battery voltage also remains constant; that's not the answer I'm looking for.) Please see photos for more details62. Alternating Current Alternating current is produced when an armature rotates about its axis in a magnetic field, as shown in the figure. Generators A and B rotate counterclock- wise at 60 Hz (cycles per second) and each generator pro- duces a maximum of 50 V. The voltage for each generator is modeled by E = 50 sin(12071) Eg = 50 sin 120nt - 4 (a) Find the voltage phase for each generator, and find the phase difference. (b) Are the generators producing voltage in phase? Through what angle should the armature in the second generator be rotated counterclockwise in order that the two genera- tors produce voltage in phase? - Magnets – N S Wire.Explain the effect of the Solenoid’s radius on the magnetic field?

Annie claims it’s the movement of the magnets that generate energy, since that’s a form of kinetic energy. Josue claim’s the electricity is generated by the power of the magnets on the outside of the moving center. Which analysis correctly describes how the electricity is generated? (a) The movement of the wire within and the magnets are needed in order for an electrical current to be generated (b) The movement of the center is what generates the electricity, the magnets on the outside don’t need to be there at all (c) The electrical current would be generated if the magnets were incredibly strong and the middle piece did not rotate (d) The placement of magnets on the outside is more important than the movement of the center for the generation of electricity
