question 179

Multiple Choice

A closed flat loop conductor with radius $2.0 \mathrm {~m}$ is located in a changing uniform magnetic field. If the emf induced in the loop is $2.0 \mathrm {~V}$ , what is the rate at which the magnetic field strength is changing if the magnetic field is oriented perpendicular to the plane in which the loop lies?

• A) \(0.080 \mathrm {~T} / \mathrm { s }\)
• B) \(2.0 \mathrm {~T} / \mathrm { s }\)
• C) \(1.0 \mathrm {~T} / \mathrm { s }\)
• D) \(0.16 \mathrm {~T} / \mathrm { s }\)
