Question

A square, 32.0- turn coil that is 11.0 cm on a side with a resistance of 0.770Ω is placed between the poles of a large electromagnet. The electromagnet produces a constant, uniform magnetic field of 0.550 T directed out of the screen. As suggested by the figure, the field drops sharply to zero at the edges of the magnet. The coil moves to the right at a constant velocity of 2.70 cm/s. A shaded, rectangular region of uniformly distributed dots signifying a magnetic field out of the screen, and a clear region to the right of the shaded region. Inside and near the middle of the shaded region is a smaller square coil moving to the right with velocity V. The coil is labeled as having N turns. What is the current ?1 through the wire coil before the coil reaches the right edge of the field? Define counterclockwise current as positive and clockwise current as negative. ?1= A What is the current ?2 through the wire coil while the coil is leaving the field? ?2= A What is the current ?3 through the wire coil after the coil leaves the field? ?3= A What is the total charge magnitude ∣Δ?∣ that flows past a given point in the coil as it leaves the field? ∣Δ?∣= C
