question 115

Multiple Choice

A flux of $4.0 \times 10 ^ { - 5 } \mathrm {~T} \cdot \mathrm { m } ^ { 2 }$ is maintained through a coil of area $7.5 \mathrm {~cm} ^ { 2 }$ for $0.50 \mathrm {~s}$ . What emf is induced in this coil during this time by this flux?

• A) \(3.0 \times 10 ^ { - 5 } \mathrm {~V}\)
• B) \(4.0 \times 10 ^ { - 5 } \mathrm {~V}\)
• C) \(2.0 \times 10 ^ { - 5 } \mathrm {~V}\)
• D) \(8.0 \times 10 ^ { - 5 } \mathrm {~V}\)
• E) No emf is induced in this coil.
