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 2.10 x 10* T directed toward the left of the page, what is the magnitude of the torque on the coll? Hint: The area of an ellipse is A- nab, where a and b are, respectively, the semimajor and semiminor axes of the ellipse. N.m 30.0 cm- Need Help?

MY NOTES PRACTICE ANOTHER A rectangular coil consists of N-160 closely wrapped turns and has dimensions a 0.400 m and b-0.300 m. The coil is hinged along the y axis, and its plane makes an angle - 30,0° with the x axds (figure). ASK YOUR TEACHER (a) What is the magnitude of the torque exerted on the coll by a uniform magnetic field 8-0.390 T directed in the positive x direction when the current is -1.20 A in the direction shown?
