Question
In the figure below, a region with a constant magnetic field equal to 0.41 T out of the page is shown. A single turn, rectangular loop of wire moves into this region with a speed of 19.5m/s. The dimensions of the loop are a=0.71 m and b=0.45 m. The loop has a resistance of 2.43 . by While the loop is moving into the region of constant magnetic field, the direction of the induced magnetic field in the to the left oop is: Submit Answer Incorrect. Tries 2/3 Previous Tries While the loop is moving into the region of constant magnetic field, the magnitude of the induced current flowing in the loop is Submit Answer Incorrect. Tries 1/20 Previous Tries While the loop is moving into the region of constant magnetic field, the direction of the magnetic force acting on the to the left oop is: ubmit Answer Incorrect. Tries 1/3 Previous TriesExplanation / Answer
a)
as the loop moves inside the magnetic field , its magnetic flux increases in outward direction. hence to oppose the change , the loop induces current in it to decrease the magnetic flux. the induced current flows so as to produce magnetic field in opposite direction to the external magnetic field so as to decrease the magnetic flux.
hence induced magnetic field is in inward direction
b)
to have the induced magnetic field in inward direction , the loop must have the induced current in clockwise direction as per right hand rule
c)
down direction.
due to the induced current , the loop experience force in direction opposite to the motion so as to resist the change.
