Transcribed Image Text: An eight-turn coil encloses an elliptical area having a major axis of 40.0 cm and a minor axis of 30.0 cm (see figure). The coil lies in the plane of the page and has a 6.10-A current flowing clockwise
around it. If the coil is in a uniform magnetic field of 1.98 x 10** T directed toward the left of the page, what is the magnitude of the torque on the coil? Hint: The area of an ellipse is A
tab, where a
and b are, respectively, the semimajor and semiminor axes of the ellipse.
Apply the expression for the torque on a loop in a magnetic field to find the torque on the eight-turn coil. N • m
