Question
As shown above, a square loop of wire, 0.88 m on each side, has one edge along the positive z-axis and is tilted toward the y-z plane at an angle of 30.0? with respect to the horizontal (x-z plane). There is a uniform magnetic field of 0.33 T pointing in the positive x-axis direction.
a) What is the flux through the loop?
Wb
(b) If the angle increases to 60?, what is the new flux through the loop?
Wb
(c) While the angle is being increased, which direction will current flow through the top side of the loop?
Explanation / Answer
= BAcos
= 0.33*0.88^2*cos60
= 0.1277 Wb
new flux = 0.33*0.88*0.88*cos30
= 0.221 Wb
