Question

An eight - turn coil
encloses an elliptical area having
a major axis of 40.0 cm
and a minor axis of 30.0 cm
(Fig. P19.37). The coil lies
in the plane of the page and
carries a clockwise current of
6.00 A. If the coil is in a uniform
magnetic field of 2.00 x
10-4 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 = πab, where a and b are,
respectively, the semimajor and semiminor axes of the ellipse.
