A uniform magnetic field has an initial value of 0.45 T and a direction toward the right. A square loop of wire with side length 0.15 m is in the field and is oriented at 45° to the field direction. The magnetic field is decreased linearly to zero during a time interval of 0.13 s.

A. What is the emf generated in the wire loop during this process?

B. If the wire has a diameter of 8.4X10-4 m and a resistivity of 1.7X10-8 Ωm, what is the current flowing in the wire during this process?
