Question

A square, 20.0-turn coil that is 13.0 cm on a side with a resistance of 0.690ohm is placed between the poles of a large electromagnet. The electromagnet produces a constant, uniform magnetic field of 0.500 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 2.10 cm/s.

What is the current i1 through the wire coil before the coil reaches the right edge of the field? Define counterclockwise current as positive and clockwise current as negative.

What is the current i2 through the wire coil while the coil is leaving the field?

What is the current i3 through the wire coil after the coil leaves the field?

What is the total charge magnitude |delta Q| that flows past a given point in the coil as it leaves the field?

The image depicts a magnetic field represented by a grid of circles with dots in the center, indicating that the magnetic field vector \(\mathbf{B}\) is directed out of the screen. In the lower part of the image, it is annotated as \(\mathbf{B}\) out of the screen.

Embedded in this field is a rectangular box labeled as an "N-turn coil." An arrow labeled \(\mathbf{v}\) originates from the right side of the coil, pointing to the right, which indicates the direction of motion.

This diagram illustrates a scenario involving electromagnetic induction, where an N-turn coil moves through a magnetic field at velocity \(\mathbf{v}\), experiencing changes in magnetic flux due to its motion, which can induce an electromotive force (EMF) in the coil based on Faraday's law of induction.
