A Square Conducting Loop Is Situated Such That It Is

question 20

Multiple Choice

A square conducting loop is situated such that it is vertical, in the xz-plane. The Earth's gravitational field points downward (in the -z direction) . The loop is dropped and maintains its orientation in the xz-plane. A magnetic field pointing in the +y direction exists and is uniform with respect to time, but it varies as a function of z: B_y(z) = B₀(10 m − z) . The loop is dropped and allowed to fall under the influence of gravitation. You observe the loop from the +y direction (i.e., looking toward the −y direction) . Which of the following occurs?

• A) The situation is unclear because we do not know the initial conditions.
• B) There is a clockwise induced current.
• C) There is a counter-clockwise induced current.
• D) There is no induced current.
