question 246

Multiple Choice

A flat circular loop of radius $0.10 \mathrm {~m}$ is rotating in a uniform magnetic field of $0.20 \mathrm {~T}$ . Find the magnetic flux through the loop when the plane of the loop and the magnetic field vector are at an angle of $30 ^ { \circ }$ .

• A) \(0 \mathrm {~T} \cdot \mathrm { m } ^ { 2 }\)
• B) \(6.3 \times 10 ^ { - 3 } \mathrm {~T} \cdot \mathrm { m } ^ { 2 }\)
• C) \(5.5 \times 10 ^ { - 3 } \mathrm {~T} \cdot \mathrm { m } ^ { 2 }\)
• D) \(3.1 \times 10 ^ { - 3 } \mathrm {~T} \cdot \mathrm { m } ^ { 2 }\)
