A Rectangular Loop of Wire That Can Rotate About an Axis

question 116

Multiple Choice

A rectangular loop of wire that can rotate about an axis through its center is placed between the poles of a magnet in a magnetic field with a strength of 0.40 T, as shown in the figure. The length of the loop L is 0.16 m and its width w is 0.040 m. What is the magnetic flux through the loop when the plane of the loop is perpendicular to the magnetic field?

• A)13 × 10^-3 T ∙ m²
• B)2.6 × 10³ T ∙ m²
• C)0.80 T ∙ m²
• D)2.6 × 10^-3 T ∙ m²
• E)0 T ∙ m²
