Question
In the figure below, a region with a constant magnetic field equal to 0.45 T out of the page is shown. A single turn, rectangular loop of wire moves into this region with a speed of 16.5 m/s. The dimensions of the loop are a=0.44 m and b=0.7 m. The loop has a resistance of 1.89 .
While the loop is moving into the region of constant magnetic field, the magnitude of the induced EMF is? (Not 3.267)
While the loop is moving into the region of constant magnetic field, the magnitude of the magnetic force acting on the loop is?
While the loop is moving into the region of constant magnetic field, the direction of the magnetic force acting on the loop is? (Not left)
I already asked this question once and it was WRONG. Please give me the correct answers.
Explanation / Answer
emf = rate of change in flux
emf = B*a*v
emf = 0.45*0.44*16.5 = 3.27 V
=======================
magnetic force = I*a*B = (e/R)*a*B = (3.27/1.89)*0.44*0.45 = 0.342 N
