The area of an elastic circular loop decreases at a, Ask an Expert

Academics

The area of an elastic circular loop decreases at a constant rate, dA/dt = -1.46 x 10^-2 m²/s . The loop is in a magnetic field B = 0.40 T whose direction is perpendicular to the plane of the loop. At t = 0, the loop has area A = 0.285 m².

Part A

Determine the induced emf at t = 0, and at t = 2.00s.
