Question
A rectangular coil consists of
N = 100
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 axis (figure).
A rectangular coil of vertical height a and horizontal length b lies within an x y z coordinate space, where the +x-axis is to the right, the +y-axis is upward, and the +z-axis is out of the page. The bottom side of the coil lies in the first quadrant of the x z plane, and makes an acute angle ? with the +x-axis. The left side of the coil lies along the +y-axis, and the left bottom corner is at the origin. Current I flows clockwise through the coil as viewed from the left. Magnetic field vector B points to the right.
