Question

Exam 2 for Electric Drives Name Problem i (30%) Faraday's Law In the following drawing, four conductors compose a rectangular loop that is perpendicular to a magnetic field, where the top and the bottom conductors are fixed and the distance between them is a constant value Wo. 1.1) If conductor 1 is not moving, the magnetic field is evenly distributed, the flux density B is a constant B, is moving at a speed vo and remaining touching the top and bottom conductors, and the starting ive voltage does this rectangular loop have? distance between conductor 1 and conductor 2 isdo, what induct Write the voltage as a function ofW, , B,, vo, and d 1.2) If the magnetic field is evenly distributed, the flux density B is a constant B。, and conductor 2 is moving at a speed v, and remaining touching the top and bottom conductors while conductor 1 is moving at the same speed and direction with a distance of d, away from conductor 2, what inductive voltage does this rectangular loop have? Write the voltage as a function or, ,尾1%, and do . 1.3) If conductor 1 is not moving, the flux density B at a point is B- B, cos(d) with d equal to the distance rom this point to conductor 1, conductor 2 is moving at a speed v, and remaining touching the top and the ottom es this rectangular loop have? Write the voltage as a function ofW,, B,,vo, and timer 1.4) If the magnetic field is evenly distributed, the flux density B is a time-varying variable Bo cos。) , both nductor 1 and conductor 2 are fixed (not moving) and of distance do, what inductive voltage does this tangular loop have? Write the voltage as a function of constants Wo, B, and do, and time conductors, and the starting distance between conductor 1 and conductor 2 is 0, what inductive voltage d% , where either Area and B can change with time!
