ehb2 idius%20of%2Othe%20 20coil%20o1%2ON.pdf AN Sesli aku The radius of the circle forming a coil of N=105 turns is given as r=4.3cm. The coil is placed in the xy plane with its center at the origin as shown in the figure and a resistor of R=4052 is connected to its end. If B=cos(wt) (0.82ex+0.93ey+1.63ez) (T,Wb/m2) and the angular frequency is w=7632 rad/s, calculate the maximum value (peak value) of the current in the circuit in [A]. (Do not take into account the resistance and inductance of the coil wire.)
QUESTION 23 In generating electricity, a magnet, surrounded by wires connected to the electrical grid, will be made to spin, using wind, a steam turbine, or moving water. Which answer best explains what is happening in the wires during this process. a. The magnet does not need to move, and still has the capability to make electrons move in the wires that surround it. b. An induced voltage and current flow is set up in the wires surrounding a magnet due to changes in magnetic temperature. c. A magnetic field surrounds the rotating magnet, pushes on the electrons in the wires, thus giving those electrons energy per charge (voltage). d. Light from the magnet is able to push electrons out of the material that makes up the wires. In so doing, the wires are made to have a flowing electrical current.
Give two ways that you could increase the size of an induced potential difference/current.
